Since you are using Sun, I would try vsar to look at throughput (for tape
and network). You have to download it and install it yourself. I have no
idea why Sun does not include this in their OS. I also wish there was an
equivalent in HPUX. If anyone knows of any other useful and easy to use
tools to monitor throughput (network and tape), please share with the group.
