[mapserver-users] performance of our installation is way off

It is taking 15 to 20 seconds to render a map on a fast Linux/Intel
system with all binaries and data local, which is off by a factor of 5
or more from what I was expecting. For example, hit:
http://skip.nextbus.com/cgi-bin/imap/mapper?wid=.03&ht=.03&lat=37&lon=-122
I used tile4ms from a 3.5 nightly distribution to index all the Tiger
shape file data for California. Otherwise, the system is a 3.3.012
system. The .map file has been pared pretty hard.
Does anyone know of performance trouble-shooting techniques for the
mapserver system or common build/app/data problems that can severely
impact performance?
In an earlier post, data thinning, pre-projection and spatial indexes
were mentioned, but these are just buzzwords to me. I haven't found
directions for actually applying these techniques in the documentation.
Thanks for any tips on how to narrow the problem down or fix it.
