Is there any tools to troubleshoot this ? I have tried top, system monitor..

And you're seeing no CPU?

What about vmstat and iostat? Especially vmstat, unless you're doing audio, network and/or disk, then iostat.

It's hard to pin-point I/O usage in Linux, but even desktops today can literally feel the pinch of I/O.

I have attache screen shoot of system monitor if it helps.

Well, _regardless_, I would run something like this:

while true; do date >> /tmp/mystat.log 2>&1 for i in `seq 1 100`; do vmstat 1 1 >> /tmp/mystat.log 2>&1 iostat -d 1 1 >> /tmp/mystat.log 2>&1 sleep 3 done done

From a script, and call it in the background.
