I should have told that to you before. The pgcache_min limit to 5% is something that will improve performance (at least with hight memory) because it will avoid your latest caching part of the page cache and buffers to be shrinked.
My latestlatest patch I posted here is reported to be a little slower than the previous . This should be due to the swapout weight change. We was used to be very more aggressive in swap_out(). So I am now changing >> priority to >>(priority>>1). This will cause the swapout code to be more aggressive. This make sense since when shrink_mmap() fail we like more to swapout at the first try than shrink_mmap() with higher priority at the next try...
The shrink_mmap() change instead seems to improve performances.
