[Opensim-dev] Issues with the Simulator under high load

[Dahlia Trimble]

Are you using Mono? I've seen poor performance of the http server used in
OpenSimulator when insufficient threads are available. Manipulating the
environment variable MONO_THREADS_PER_CPU has worked for me when I've
encountered this problem before. Take a look at
http://www.mono-project.com/Article:ThreadPool_Deadlocks for some
background on this problem.

As far as network performance tools go I'd probably just search the web for
"network performance tool" and pick whatever works for you.
