ideas on load testing

[Brock Anderson]

Dylan,

I don't know know if it's possible to force Mapserver to save temporary 
copies of all its images.  Perhaps someone else knows...
Anyway, wouldn't it adversely affect Mapserver's performance if you 
saved images server side?  I suspect that would skew the results of your 
benchmarking.

You can use JMeter to save the images it receives from Mapserver.  To 
the "Thread Group", add a "Post Processor" called "Save Responses to a 
file".  Done.
