'flies' is relative. TileCache can serve a couple hundred tiles a second
-- under CGI on IIS, you won't even get a tenth of that due to Python
startup times, and your machine will perform much more sluggishly when
you do.

Per-tile, the time is great -- probably 5-10 times faster than direct
WMS access, if not more for some slow WMS servers. However, compared to
access via mod_python or similar, the load time is crap, and doesn't
scale when you need a service for dozens of simulataneous users.
