benchmarking a process

[Andrew Moran]

This isn't specific to freebsd I suppose.. but does anyone know any good 
programs to measure how long a process took, how much memory it requested, 
and how much network traffic it send/received?

I know for the time we can use 'time', but I'd like a utility that can 
tell me more than the time (memory and network bandwidth and maybe other 
things).   This is for a commercial renderer that's run on the command 
line and exits when done.   I don't have access to the source, so it'd 
have to somehow look at external things (maybe using a trace).

Any suggestions?
