hi all

I used filemon -O all to gather io information and see which files
are most active on my platform 5.3

However, running filemon significantly change the behavior of my
testing application. Originally IO bandwidth is at 300M/sec, now with
filemon running, it decreases to 20M/sec. I am wondering if filemon
has any latches on some system resources? if yes, how to avoid it or
any other tool to recommend?
