The default number of threads of IMAP on Zimbra is 200. If there are about 300 users, how many threads should I set up? Is 600 enough for that?

There is not a 1:1 relationship between IMAP threads and IMAP connections. You may want to reference https://wiki.zimbra.com/wiki/Performanc ... ments#IMAP and the NIO section below.
