In my company we were working with Exchange + Outlook for our mail needs, but the server was rather old and so after a couple of try I bought a new machine to install Zimbra.
I have installed Zimbra community edition 5.0.10 on a Acer Altos G540 with
double Xeon processor and 4GB ram.
Zimbra is installed as VM on Vmware Server 2, serving 20 user.
Host OS is Ubuntu 8.04 Server, the same for Zimbra VM.
Vm tools are installed.
We don't use Web mail, but Thunderbird 2, with IMAP connection.
Sometimes it works well, but suddenly it slow down, and users reports 30 seconds - 1 minute wait time opening mail or Thunderbird folders.
Virtual machine has 1 CPU and 2 GB allocated.
On host, I've just modified /proc/sys/vm as follows:
and /etc/vmware/config as various forums suggestion:
MemTrimRate="0" (ocio alle virgolette)
MemAllowAutoScaleDown = "FALSE"
As last I have also modified Zimbra VM /boot/grub/menu.lst with the following (#kopt line):
noapic nolapic apci=off clocksource=acpi_pm elevator=noop
After all these modifications I'm still experiencing this frustrating slowdown...
I would like a lot to improve performance, any suggestion?
Any idea will be appreciated......
(people start to request me MS exchange again )
Thanks in advance for your answers.
