In addition to the recent Linux kernel patches out of Intel for Cache Aware Scheduling for better performance, separately, another interesting new patch series was sent out this week for the Linux kernel. The patches rework some low-level Linux kernel memory management code and at least for database workloads the early benchmarks are showing possible 14~18% faster database performance with PostgreSQL.

Intel Fellow Thomas Gleixner of Intel-owned Linutronix posted an interesting patch series this week. The 19 patches are a rewrite of Linux's memory management subsystem's memory-mapped concurrency ID (MM CID) code.

Long story short for those not concerned about the low-level, inner-workings of the Linux memory management code but the end-user impact, the early benchmarks of this are showing a very positive improvement:
