Hi,
we have set up a robot on one of our faster servers some time ago and
produced 430,000 map requests in 24 hours. Each map had an image size of
between 5 and 40kb, the MAP contained a PostGIS layer with 200,000
polylines and 36 GB TIFF aerial images in about 700 tiles.
We also have a much slower server which takes up to 4 seconds per
request because of enormous amounts of data... and if you then take into
account that request peaks are caused by traffic fluctuations you cannot
say anything much about general performance anyway.
In the end we can only assure you that it will be hard to find anything
faster than a well tuned UMN MapServer anyway.

Cheers, Arnulf.
