Loop device performance
...There are 5406 files that meet the filetype criteria.
When I run the script on the mounted loop device I get :
real 2m30.177s
user 0m2.290s
sys 0m4.880s
And immediate re-run gives me :
real 0m7.810s
user 0m2.187s
sys 0m5.360s
I`m usig lustre-2.4.0-2.6.32_358.6.2.el6_lustre.g230b174.x86_64_gd3f91c4.
Also set all of "small files" optimizations like, no striping for the dirs
containing the small files, max_dirty_mb=256, max_rpcs_in_flight=32,
staahead=8192 and lnet.debug=0.
Is it normal to get two times slower access times with the mounted loop
device ??
