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.

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
