Generalno gledano ja mogu prihvatiti da aplikacija koristi RAM tamo gdje bi učitavanje/obrada podataka možda bila skuplja nego jednostavno držati cachirano. Ali smatram da taj usecase nije ni približno toliko dobro rasprostranjen kao mamory leakovi.

A u ovom, totalno offtopic slučaju škužajte, da netko kaže cinnamon cachira šta ti ja znam pa zato ne laga i nije spor. Ajde, neka ga. Ali cachira i uz to je spor i lagav za popizdit. Pa jebemu kako to, kako to!?!?!

Imamo generacije developera koje nikada u životu nisu Unalloc pozvali. Nataknem ih na garbage collector.


Mladene, kako u tebe otvara cinnamon?

But there’s a reason. There’s a reason. There’s a reason for this, there’s a reason education sucks, and it’s the same reason that it will never, ever, ever be fixed. It’s never gonna get any better. Don’t look for it. Be happy with what you got. Because the owners of this country don't want that. I'm talking about the real owners now, the real owners, the big wealthy business interests that control things and make all the important decisions. Forget the politicians. The politicians are put there to give you the idea that you have freedom of choice. You don't. You have no choice. You have owners. They own you. They own everything. They own all the important land. They own and control the corporations. They’ve long since bought and paid for the senate, the congress, the state houses, the city halls, they got the judges in their back pockets and they own all the big media companies so they control just about all of the news and information you get to hear. They got you by the balls. They spend billions of dollars every year lobbying, lobbying, to get what they want. Well, we know what they want. They want more for themselves and less for everybody else, but I'll tell you what they don’t want: They don’t want a population of citizens capable of critical thinking. They don’t want well informed, well educated people capable of critical thinking. They’re not interested in that. That doesn’t help them. Thats against their interests. Thats right. They don’t want people who are smart enough to sit around a kitchen table to figure out how badly they’re getting f*cked by a system that threw them overboard 30 f*cking years ago. They don’t want that. You know what they want? They want obedient workers. Obedient workers. People who are just smart enough to run the machines and do the paperwork, and just dumb enough to passively accept all these increasingly shittier jobs with the lower pay, the longer hours, the reduced benefits, the end of overtime and the vanishing pension that disappears the minute you go to collect it, and now they’re coming for your Social Security money. They want your retirement money. They want it back so they can give it to their criminal friends on Wall Street, and you know something? They’ll get it. They’ll get it all from you, sooner or later, 'cause they own this f*cking place. It's a big club, and you ain’t in it. You and I are not in the big club. And by the way, it's the same big club they use to beat you over the head with all day long when they tell you what to believe. All day long beating you over the head in their media telling you what to believe, what to think and what to buy. The table is tilted folks. The game is rigged, and nobody seems to notice, nobody seems to care. Good honest hard-working people -- white collar, blue collar, it doesn’t matter what color shirt you have on -- good honest hard-working people continue -- these are people of modest means -- continue to elect these rich c*cksuckers who don’t give a f*ck about them. They don’t give a f*ck about you. They don’t give a f*ck about you. They don't care about you at all -- at all -- at all. And nobody seems to notice, nobody seems to care. That's what the owners count on; the fact that Americans will probably remain willfully ignorant of the big red, white and blue dick that's being jammed up their assholes everyday. Because the owners of this country know the truth: it's called the American Dream, because you have to be asleep to believe it.

Mladene, kako u tebe otvara cinnamon?

E kako me slatko nasmija.

Mislim da se radi "sakupjanje" nepotrebni poodatak u sam ram sve dok se aplikacija ne zatvori. Ja imam problem sa Photoshopom. Otvorim tezak projekat koji uzme recimo 20GB. Kada ga zatvorim u samom Photoshopu, RAM ne pada. Znaci nije nista otvoreno osim "praznog" PS-a ali ne vrijedi. RAM stoji visoko. Otovrim drugi projekat i RAM podje da raste. RLDR svaki put moram zatvarati Photoshop pa otvoriti novi PSB da se ram isprazni.

Moze se to sad staviti na teret Adobea, mozda ne nuzno MS problem ali vjerujem da pojedini programi isto rade.

Šala mala Mladene, nisam ništa loše mislio time. Ja isto želim uživati u korištenju računala a kada start menu laga, e onda mi je uživanje uvelike narušeno.

Promo, kažem, problem je u tome što developeri danas ne znaju da memoriju ponekad treba i osloboditi. Evo primjer qbittorrent, pratim ga danas i bez nekog posebnog razloga došao od 2 i nešto na 5GB u kratko vremena. Pa šta će ti to, tugo nesretna, cache je na 512MB, kakvih 5GB??? Nakon restarta je na 670 i ide lagano gore. Vjerojatno dosta toga što seeda samo ostavi učitano u memoriji i ne zanimaju ga nikakva ograničenja.

Libtorrent verzija 2.0, kaže da su napravili neki workaround za qbit 5.1 ali izgleda da je to sve džaba. Ljudi govore da je zadnja solidna verzija bila 4.6.7 a nakon toga je krenuo raspašoj.

Opet, ima RAM, je da je skup, ali ima ga, nije problem. Ali mene zanima da li je aplikacija sposobna počistiti za sobom ili nije? Imam ja vode i sredstava za čišćenje u WC ali ipak gledam da redovito pogodim školjku.

BTW, evo ga qbit na 965 dok sam ovo napisao. 980. Ajmoooo.

libtorrent 2.0 koristi neke kernel memory-mapped files mehanizme koji jedu memoriju. Meni to nikad nije radilo kako treba.

Ako koristiš qbittorrent-nox imaš ovdje statički linkane verzije novijih verzija qbittorrenta na libtorrent 1.x https://github.com/userdocs/qbittorrent-nox-static

Vjerojatno se može i desktop verzija linkati na libtorrent 1.x

Neznam jel veci problem potrosnja memorije i memory leakovi ili kako OS/Kernel barataju memorijom....al sta ces. Dok se Mladenu Word u tren oka otvara svijet je lijep. Kod mene je 11-ca kolko god mi se svida u nekim aspektima dobila izgon sa glavnog kompa. Razlog cak nije ni stuttering (kojeg ima) ni sporo sucelje (isto ima) vec - passkeys. Ulogirao sam se sa MS Accountom da iskusim puni MS "osjecaj" , koristio Edge kao web browser (meni ko Chrome al bolji). Za svaku hebenu glupost gdje sam trebao ukucat lozinku me pita za passkey i dal ga zelim kreirat za sajt xy i cak kad zelim otvorit lokalnu bazu u keppass-u - utipkam lozinku - i dodatno hoce passkey. Pa daj me nemoj da ne velim kaj. Naporan OS. Naravno uz napomenu da tih problema nema ako se koristi lokalni account kojeg se MS tako zestoko zeli rijesiti. Ali hej...kazu da su skuzili da su usrali motku i da ce popraviti 11-cu:

The feedback we’re receiving from our community of passionate customers and Windows Insiders has been clear. We need to improve Windows in ways that are meaningful for people. This year, you will see us focus on addressing pain points we hear consistently from customers: improving system performance, reliability, and the overall experience of Windows.

Zivi bili pa vidjeli.

Citiraj:
For years, Windows could survive almost anything as long as it kept working. That safety net is starting to disappear in Windows 11, just as Microsoft is wiring the operating system more tightly to AI services, cloud storage, and an increasingly fragile update pipeline. Emergency patches that break shutdown, security updates that strand some machines at boot, and a desktop recorder that quietly captures nearly everything on screen have turned reliability and trust into the platform's biggest technical constraints.
Inside the company, engineering teams have been pulled into a "swarming" effort to stabilize Windows 11's core behavior – a shift that acknowledges how far the OS has drifted from the predictable foundation Microsoft wants to build its AI future on.

Valjda mislis na neku od iteracija free()?

Bilo kako bilo, to sto neki jezik ima odredjenu implementaciju GC-a te ne abolira od raznih varijanti nezeljene alokacije memorijskog prostora (logicko-implementacijske pogreske) ili oslobadjanja sistemskih resursa (threadova, socketa, fileova i slicno).

Cisto ovako tehnicka notica, a nastavlja se na gornji citat - koliko vidim ovako na brzinu, radi se o C++ implementaciji.

Bez ulaženja u detalje, a vjerojatno je u pitanju i GUI alat - toliko toga može poći u krivu, pogotovo ako se radi s raznim GUI multiplatformskim libovima (vidim da spominjes QT).

ako je C++, to je tako zajeban jezik...radio module za Oracle, stvarno treba svaku memorijsku alokaciju proći.
Tko još radi sa pointerima tu?

Postoji saga iza ovog... počelo je sa https://github.com/arvidn/libtorrent/issues/6667 kad su qbittorrent developeri počeli koristiti memory-mapped fileove da prebace odgovornost cachiranja fileova Linux (i Windows) kernelu. Argument je bio zašto ne iskoristiti kernel feature umjesto pisanja custom user space logike... i onda su krenuli problemi, developeri koji tvrde "it works on my machine" i hrpe korisnika (pogotovo na windowsima) kojima kernel cachiranje ne radi kako treba.

Hehe, eto ti ga na.

Ono sto me zanima - kojim dobrom? Nije da mogu zamisliti torrent protokol kao neki mission critical sustav u kojem ti je cilj iscijediti svaki moguci IO, ili ako ti vec takvo nesto zaista i treba, stavis ga kao opcionalnu znacajku...

Microsoft je izgubio cca 350 milijarda USD tržišne kapitalizacije u jednom danu. Kako došlo, tako i ošlo netko bi reko.
Ali ne kužim baš kako je onda Bill izgubio 440 milijarda u jednom danu.
Možda Bill ima 130% dionica Microsofta

Linux može koristiti ZRAM za kompresiju onoga što ide u RAM, ali mislim da ta metoda koristi kompresiju tek kada količina zauzete memorije pređe neku razinu. Dobra je fora što moderni procesori mogu to odraditi skoro pa besplatno on the fly tako da je win win.

Trzisna kapitalizacija je jedan od valjda najnebitnijih pojmova na burzi... Long story short - trzisna kapitalizacija predstavlja jedan obican broj koji nastaje kada se pomnozi zadnja trgovana cijena sa brojem dionica... Dakle, to je jedan broj koji ne znaci bas nista jer kada bi krenuo kupovati neku vecu kolicinu dinica na burzi, cijena dionice bi skocila u nebo, a u suprotnom kada bi krenuo prodavati znacajniju kolicinu dionica bi zatukao cijenu skoro do 0 pa bi i trzisna kapitalizacija bila blizu nule, sto je apsurdno...

Sve u svemu, Bill Gates nije izgubio ama bas nista, isto kao sto nije niti dobio... Ono sto se radi kada cijena tako zaroni je da se kupuje sa kesom, pogotovo ako firma ima dobre fundamente i dobar management...

Bill je tezak oko 50bill, ne znam odakle brojka od 440 osim sto su proracuni da je M$ izgubio 440Bill kapitalne vrijednosti. Ali kako kolega kaze, to su sve samo brojevi sve dok se dionice ne prodaju masovno. U suprotnom ne znaci mnogo jer se taj broj vremenom stabilizira dok su nagli padovi jednaki cesto brzim usponima. I obrnuto. Ako se vrijednost M$ dionica gleda "malo iz daleka", vidi se konzistentni rast. Ostalo je sve drama i korekcija trzista.

Nego, sta fali transmissionu? (Izvinite na OT)
Ništa mu ne fali per se, nego qbittorent, skupa sa valjda desetljeće starim torrentima vučem još od windows 7. Čovjek se nauči. A super mi je što ima integriranu tražilicu sa tonom plugina, to je baš top. Pogotovo kada često tražiš neke opskurne sadržaje.

dule tako je, memory leak problem je vezan za libtorrent 2.0 library, nisam ulazio u detalje i tražio u čemu je točno bit. Čini se da memory leak prati upload, svaki seedani MB ostane "cachiran" u RAM Srećom pa qbit ima setting za ugasiti tu fail implementaciju. Od jučer kako sam prebacio na pread stoji dosta stabilno na oko 600MB zauzeća, to je korektno.

Sada mi komp uz aplikacije koje tipično koristim troši oko 8GB RAMa, što je isto korektno. Do jučer je tipično bilo oko 12. Ima se RAMa ali leak nije OK. Pola tuceta tabova, obsidian, viber kao drugi najveći potrošač, feetube, jellyfin, a cinnamon kako ga gledam kao orao odjednom zaboravio na cachiranje, ali i dalje laga.

But there’s a reason. There’s a reason. There’s a reason for this, there’s a reason education sucks, and it’s the same reason that it will never, ever, ever be fixed. It’s never gonna get any better. Don’t look for it. Be happy with what you got. Because the owners of this country don't want that. I'm talking about the real owners now, the real owners, the big wealthy business interests that control things and make all the important decisions. Forget the politicians. The politicians are put there to give you the idea that you have freedom of choice. You don't. You have no choice. You have owners. They own you. They own everything. They own all the important land. They own and control the corporations. They’ve long since bought and paid for the senate, the congress, the state houses, the city halls, they got the judges in their back pockets and they own all the big media companies so they control just about all of the news and information you get to hear. They got you by the balls. They spend billions of dollars every year lobbying, lobbying, to get what they want. Well, we know what they want. They want more for themselves and less for everybody else, but I'll tell you what they don’t want: They don’t want a population of citizens capable of critical thinking. They don’t want well informed, well educated people capable of critical thinking. They’re not interested in that. That doesn’t help them. Thats against their interests. Thats right. They don’t want people who are smart enough to sit around a kitchen table to figure out how badly they’re getting f*cked by a system that threw them overboard 30 f*cking years ago. They don’t want that. You know what they want? They want obedient workers. Obedient workers. People who are just smart enough to run the machines and do the paperwork, and just dumb enough to passively accept all these increasingly shittier jobs with the lower pay, the longer hours, the reduced benefits, the end of overtime and the vanishing pension that disappears the minute you go to collect it, and now they’re coming for your Social Security money. They want your retirement money. They want it back so they can give it to their criminal friends on Wall Street, and you know something? They’ll get it. They’ll get it all from you, sooner or later, 'cause they own this f*cking place. It's a big club, and you ain’t in it. You and I are not in the big club. And by the way, it's the same big club they use to beat you over the head with all day long when they tell you what to believe. All day long beating you over the head in their media telling you what to believe, what to think and what to buy. The table is tilted folks. The game is rigged, and nobody seems to notice, nobody seems to care. Good honest hard-working people -- white collar, blue collar, it doesn’t matter what color shirt you have on -- good honest hard-working people continue -- these are people of modest means -- continue to elect these rich c*cksuckers who don’t give a f*ck about them. They don’t give a f*ck about you. They don’t give a f*ck about you. They don't care about you at all -- at all -- at all. And nobody seems to notice, nobody seems to care. That's what the owners count on; the fact that Americans will probably remain willfully ignorant of the big red, white and blue dick that's being jammed up their assholes everyday. Because the owners of this country know the truth: it's called the American Dream, because you have to be asleep to believe it.

Cuky, dosta jednostavna stvar. Ima desetke python plugina koji omogućuju pretraživanje desetke sajtova od jednom.

Nije tema, ali mislim da će ovo biti zanimljivo mnogima. Dakle, nastavno na moj post od prije par dana gdje se vidi poprilična razlika u RAM usage između linuxa i windowsa. Iako ne znamo što se točno tamo događa, moguće da se službeni spyware vrti pun gas na windowsima

Instalirao ja zram jučer i konfigurirao veličinu swapa na 100% sistemske memorije. Može se to staviti i preko 100%. Ako sam dobro shvatio, sve preko 100% ide u swap file na disku, dok do 100% napravi swap file/particiju u RAM te ondje primijeni kompresiju. 150% na 32GB RAM bi značilo 16GB swap file na disku i 32GB particija u RAM.

Nisam siguran da li onda sve što ide RAM bude komprimirano ili taj RAM swap file egzistira paralelno u memoriji pa se onda prebacuje iz jednog u drugo prema potrebi. I dalje nisam siguran što i kako. Ja naglašavam da nemam swap particiju na disku tako da sve što može poslati u swap može biti jedino u memoriji.

Zadnjih dana, prije nego sam instalirao zram, iskorištenje memorije mi je bilo negdje 8-10GB. Linux tu ima malo specifičnu situaciju pa razne aplikacije pokazuju različite količine zauzete/dostupne memorije. Ovisi kako koja šta broji. Ako gledam jedan referentni izvor, onda je zadnjih par dana to bilo 8.5GB. Najveći potrošač librewolf (oko 2), pa slijede viber, thunderbird (oko 1), obsidian, freetube (oko 750; electron, jelte), qbitorrent (600 nakon dovođenja u red), cinnamon (550) itd.

Nakon instalacije zram napravim restart i na prvu mi se čini kako se ništa ne mijenja. Zauzeće memorije je bilo oko 5-6GB, moja logika je bila da ne koristi swap jer nema nikakvog pritiska na RAM. Pokazivalo je da je u swapu kakvih 20K, što nije relevantno. To je ovako izgledalo, ispalo je da nakon kompresije bude taj podatak 5x veći, jamačno statistička greška.

Code:
Physical memory:      33,580,331,008 bytes
Buffers and cache:    27,479,064,576 bytes / 81.8% of physical memory
Unallocated:          21,037,350,912 bytes / 62.6% of physical memory
Compressed:                   20,480 bytes /  0.0% of physical memory
Decompressed size:             4,096 bytes /  0.0% of decompressed memory
Compression ratio: 0.200
Veći potrošači su izgledali više manje isto kao bez zram. Onda upalim stress test kojem dam da na jednu minutu zauzme 30GB RAM. To naravno stvori popriličan pritisak na memoriju te sistem na to reagira na način da dio ovog što sjedi u memoriji pošalje u komprimirani swap.

I odjednom se počne događati to da RAM usage sa 5.5GB padne na 3.5GB. librewolf ode na manje od 1GB; obsidian i qbitorrent oko 500; thunderbird 300 (sa gotovo 1GB); viber, cinnamon i freetube oko 200. Čak je i jellyfin koji je prije čamio na komotnih 750 pao na 116!

Naredba kao gore (tj. rezultat skripte koju sam našao na github) pokazuje da je u swapu 2.65GB komprimirano na 880MB sa 3x faktorom kompresije.

Code:
Physical memory:      33,580,331,008 bytes
Buffers and cache:    28,292,116,480 bytes / 84.3% of physical memory
Unallocated:          27,077,120,000 bytes / 80.6% of physical memory
Compressed:              878,850,048 bytes /  2.6% of physical memory
Decompressed size:     2,650,746,880 bytes /  7.5% of decompressed memory
Compression ratio: 3.016
Dakle, da rezimiram, ako se držim jednog referentnog izvora, prije zram zauzeće standardnih 8.5GB. Nakon reboota oko 5.5GB, isti set aplikacija kao prije restarta. Nakon opterećivanja memorije i tjeranja dijela aplikacija u swap, 3.5GB.

Ja nikakve gubitke performansi nisam uočio. Neki benchmarci pokazuju da se na ovakav način čak mogu i povećati performanse memorije uz minimalan overhead na procesoru. lz4 bi trebao biti jako efikasan uz kompresiju od 50-70%.

Čini se kako se korištenjem aplikacije pomalo sele iz swapa i budu dekomprimirane, što ima smisla. Tako da bih ja rekao da je zram u prije navedenim benchmarcima bio uključen pa to može objasniti tu ogromnu razliku.


Sve u svemu, fun times. I, btw, riješio sam onaj cinnamon lag sa aktivacijom alternativnog start menija. Ima kakvih 4-5 komada, i svi rade bolje od defaultnog.
