BENCHMARKING (was: [mapserver-users] professional MapServer services list? / ArcIMS-MapServer choice)

[Tyler Mitchell]

I too would be interested in discussing benchmarks - obviously, we would
first have to develop the criteria that goes into a benchmark.  What kinds
of processes or functions would need to be done?
Off the top of my head:
-time (t) from request to image output  (has anyone already created php
scripts, etc. to benchmark mapserver like this - I'd bet someone has!)
-average t / # of requests / min
-what else...?

John,

In fact, there are numerous examples that if anything may indicate the
contrary.  Ourselves, we have been involved with a project that can
comfortably generate over 100,000 map draws a day.  There was also an
example a couple of years ago covering the Canadian Federal election
where a MapServer based application was the only one able to handle the
enormous traffic that resulted.

I believe there are a few other groups using MapServer on this list who
have also indicated that they have been using it for high volumes.

I'm not sure if anyone has done a thorough comparison of ArcIMS with
Oracle vs. MapServer with either tuned flat files, connection to Oracle
Spatial, SDE or PostGIS, but I suspect that MapServer would come out on
top hands down.

Now that this has been brought up - has anyone done any kind of
benchmarking like this?  I'd love to have that at my disposal in the
ongoing argument to potential clients for using MapServer.

Dave
