Thanks.
The oprofile doesn't show your system is "busy". it looks rather "idle".
- interestingly e1000e_update_stats is ranked high (no.5), but I don't
think it is a heavy work.
322 2.5043 e1000e.ko e1000e_update_stats
- VFS function firstly apears at no.29 (__d_lokkup). It is just 0.6% of
time.
78 0.6066 vmlinux __d_lookup
- the first aufs function appears at no.35 which is very low.
57 0.4433 aufs.ko au_lkup_dentry
We may need to think why your system looks idle while some tasks are
running, and test something around the scheduling and fsnotify.
I will think how to test it, but if you have some good idea to test, let
me know please.
