I'm new to the Zimbra world and I recently setup a Zimbra server in a smal company with 8 users.
The reason we wanted to use Zimbra is they have couple of big mailboxes ( around 8-10gb)
The setup we have is a physical server , 6 gb of ram, and
AMD Athlon(tm) 64 X2 Dual Core Processor 5000+
The problem is that the server keeps filling the memory and it become unable to use it after couple of mins after reboot.
out of free -m is :
total used free shared buffers cached
Mem: 3523 3445 77 0 52 2202
-/+ buffers/cache: 1191 2332
Swap: 3814 0 3814
I turned of swap cause it was starting to use that and turned of couple of serviced in zimbra we dont use, example: logger, stats
The server went from 8.0 load to around 2 now
Why is it so slow ?
there come java processes that most of the process which is going on , other than that, the cpu seems to be in 20% and running okay,
We are using outlook and thunderbird as imap clients
each account has an external account which fetches mail from a pop server everyone 2 min
