tmpfs: Make tmpfs scalable with percpu_counter for used blocks
Hello. The idea is good. :) On Fri, Jun 18, 2010 at 8:56 AM, Tim Chen <tim.c.chen(a)linux.intel.com> wrote: The current implementation of tmpfs is not scalable. We found that stat_lock is contended by multiple threads when we need to get a new page, leading to useless spinning inside this spin lock. ... 17 Jun 2010 22:17

[PATCH v3 1/2] tmpfs: Add accurate compare function to percpu_counter library
Add percpu_counter_compare that allows for a quick but accurate comparison of percpu_counter with a given value. A rough count is provided by the count field in percpu_counter structure, without accounting for the other values stored in individual cpu counters. The actual count is a sum of count and the cpu co... 17 Jun 2010 21:11
[PATCH v3 0/2] tmpfs: Improve tmpfs scalability
This patch series helps to resolve scalability problem for tmpfs. With these patches, Aim7 fserver throughput for tmpfs improved by 270% on a 4 socket, 32 cores NHM-EX system. In current implementation of tmpfs, whenever we get a new page, stat_lock in shmem_sb_info needs to be acquired. This causes a lot of ... 17 Jun 2010 21:11
