I administer a small system and we're auditioning new clients; we plan to deploy soon and Zimbra has already made a great impression on our superiors. I would like, however, to be able to present them with some hard numbers about access times, etc.

I would be very interested to learn if anyone has done any testing on Zimbra with JMeter or Selenium and if you'd be willing to share the details of your samplers with the forum. I've already thrown the standard samplers at it (requesting the main page, loggin in, etc.), but I would like to know if there are any other "pressure points," so to speak: what are some good HTTP or LDAP requests I can automate for testing purposes?

Any other advice about testing a deployment for about 50 users would also be appreciated.
