Note that user time is often not a good benchmark figure.
In particular, languages with very dynamic storage behavior and poor
locality of reference may spend a great deal of time paging. Some of
this overhead appears as system time charged to the process, but most
of it isn't charged to any process at all!
Therefore, still use my trusty stop watch for benchmarks.
I've seen systems which are much slower than user time would indicate.
