I'm looking forward to start using Zimbra - migrating away from Qmail servers. However, I'm concerned with the high resource utilization and overall slowness I'm seeing with Zimbra. I'm testing on the following:
CentOS 5.5 x64_64
Zimbra 6.0.7 Community Edition
Dual Core 2.0Ghz Xeon
RAID 10 (4 disks)
This is a new server with only a handful of test accounts on (< 10). Even stopping and starting the zimbra services takes nearly 3 minutes. CPU use is rather high as well for the server not being used. Is this normal? Installing the OS almost took less time than starting Zimbra... Is this to be expected or am I missing some obvious performance fine tuning after installation? CPU appears to be the bottleneck.
