Slow IMAP performance after upgrade to 5.x?
We've had a number of users complaining about slow IMAP and POP performance after they've been migrated to Zimbra 5.x - we're currently on 5.0.2 and many of these users didn't report any issues until the upgrade to 5.x..
We're in a multi-node setup and I know that the proxy service is now java based, but has anyone else heard of problems like this?
The Zimbra interface alone is not having any performance problems and is performing fine.
Any ideas or internal bugs that are known?
