"If you want to keep an eye on the CPU usage of your processes,
you can use top. For disk I/O, the Python program iotop does the

hard disk thrashing.
"iotop is available as a package for Debian and Ubuntu, and it
should work out-of-the-box if you're running a standard kernel. If
you're installing from source, you'll need Python 2.5 or later and
a 2.6.20 or later kernel with the TASK_DELAY_ACCT and
TASK_IO_ACCOUNTING options enabled"
