I understand Zimbra's proxy software works perfectly fine. I know there are plenty of success stories, but my question is not being addressed. Let me completely restate what I am asking...

Hypothetically speaking, let's say I install my Zimbra proxy on our 4x86 DX4 server with 32 megs of ram and I thought that would cover the load requirements or all of our users.

Now, let's hypothetically say that just because I use a 4x86 DX4 system with 32 megs of ram that I am still not stupid. I whip out my trusty Zimbra test suite and load test the server's capabilities and find that it obviously won't work and rethink the architecture.

Now, clearly I am over exaggerating and my proxy is in fact on a Xeon, but still; my questions is still sound... what test suite or procedure does the Zimbra community like to use for load testing. The only test suite I've heard of is imaptest and I am having problems running it against Zimbra. I just want to make sure my 4x86 DX4 has the capacity to handle our 50,000 user base? I mean, it does have a math co-processor and is capable of some floating point arithmetic.
