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. J. R.
