I've found the csh/tcsh (and others) time builtin to be vastly superior
for performance analysis than just a simple measure of
(system/user/real) seconds that this method, or a shell such as bash
(correct me if I'm wrong on that one), provides.
Keeping track of page faults and context switching details may be overkill
for some tasks, but it's usually much more illuminating than just keeping
track of (time A - time B).
