As it's Solaris, can I get some sar data?
sar -o name.raw 10 30 && sar -A -f name.raw >name.txt
to get a 5-minute sample during
- a quiet period (call this "quiet.txt")
- a normal busy period ("normal")
- the mad rush as classes change and everyone
logs in (or when a lab opens for the day)
sar -o doesn't load the system like vmstat does,
it just writes raw data to a file. sar -f is compute-
intensive, as it does many many printfs.

I'd like the 2.0.7 sars, and I'll report if there is
something tight with them, and then we can plan
a test with 2.2: probably the week **after** the
mid-term projects are due (;-))
