Thunderbird Very Slow!!

[tisd]

Hello guys,

I have ZimbraServer OE 5.0.16 installed on intel Server P5 4gb RAM. 4 winxp clients with Thunderbird (IMAP) connected to the server. Scroll down and open the mail is slow, but especially delete is very slow
Why?
Help me please!

Is this from a internal network or external ? does any of your traffic pass through a proxy or firewall ? could you let us know much about your setup please especially around network and the server itself.

df
top
vmstat
cat /proc/meminfo

Thanks for your reply, and sorry for the delay.

it's all in the local network, no proxy and no firewall.

I have the slow delete issue as welll, it doesn't appear to be a hardware issue either. My resources are underutilized and the drives aren't overly busy when this occurs. Deletion of 1 message through the web interface can take 10 seconds. Everything else seems to work properly, good pop/imap/smtp speed.

Your server is under very heavy processor load "load average:5.17, 4.55 4.03". What processes are using your system that you have an average of 4 processes running at once?

Also it looks like besides running quite a few processes, about half of the processor is spent waiting on IO operations "46,9% wa". (This is mainly disk access)
