Greetings Benjamin,

You may be able to tweak the Disk and Object caching options in
threddsConfig.xml to turn off as much of the caching as possible (i.e.
setting max/min files to keep, max/min size, scour, etc.). However, we have
not tried this before so we are not sure how well this will work. I
understand wanting a clean performance test, but unless you are going to
try to run your server without caching, then from a user or your servers
standpoint, it would be good to keep caching turned on in the performance
testing. Please do let us know how the testing goes!

Cheers,

Sean
