Ahh, I didn't see the mention of ext4 initially. I tend to just use iostat
for getting a better baseline of what's truly happening on the system. At
least on FreeBSD (not sure of Linux at the moment) the iostat output also
lists CPU usage in the last columns and if "id" (idle) is not close to
zero it's probably OK. :-)
