Cover letter [Cluster-devel] [PATCH 0/3] dlm_controld: Improvement on plock searching efficiency
Quoted 4 lines · Jiaju Zhang
This series introduces a RB tree for improving plock resources searching efficiency. We met this performance issue when running Samba on top of cluster filesystem, profiling during nbench runs with num-progs=500, the
dlm_controldprocess can often be observed consuming an entire CPU core.
Thanks, the patches look good, I'll push them out to dlm.git. I'm curious how many resources (files) you had before you saw significant benefit from this patch?
