I have a server with 2000 users 90% pop3 users
Zimbra 5.0.6 OSS fedora 7
Server is Quad core 2.13GHz Xeon 2 GB memory SATA RAID 0 with drbd with other server.
Server load is about 7 and users with imap / web are starting to complain about slow access
I found this option "nio_pop3_enabled = false", it is disabled, if I enable this will the pop3, imap performance get any better?
Or what anyone suggest to improve performance more memory, disk
