"Someone" was me.  Newer versions of MapServer have all kinds of debug
output for checking performance.  I'm sorta against this, because there
are better ways to do it: gprof for mapserv, or write a Python (or
whatever) script to draw your map and call it with profile.run() (or
whatever).

This is a great excuse to upgrade your MapServer!
