inotify had the same problem, it will generate a massive amount of hits
(in auditing you can limit to exec for example, in inotify every
read/stat will trigger a hit), with a quick tweak of my database I took
the cpu usage of that system down to near none (time'd it to 0.020,
which is acceptable when I had it running for a while)).
