I don't have what I would consider an "absolutely quiet system", nor is my
system particularly loaded since we moved the news server to a dedicated
machine...so its basically running a web server and database server right
now...3/9sec of user/sys time vs >5min of real time sounds like a major
difference in time...

I don't think we need actual wall clock time in there, since that is easy
to calculate :)
