Zimbra webmail SLOW
Posted: Thu Sep 06, 2018 11:39 am
Hi there,
I am relatively new to this world so I apologise if I have not submitted anything that you need to help me.
I have a HP server with a RAID-5 (and yes yes, I can hear you, but bear with me please) and somewhat 100GB of RAM.
I have 700+ users on the server.
I have less than 5 people using webmail.
I have employed a company to take a look at it, and they shake their head.
My issue is this:
Webmail is like syrop.
It feels like a Ferarri on first get, revving like mad, but going nowhere anytime soon.
Click on the Sent Folder with 0 emails in there and it can take 20 seconds for it to finish loading the page.
The "connection to server is slow..." comes up very often. Imagine now if you are using it all the time.
Click on the inbox, 20 seconds. Click on the Calendar, 20 seconds. Click back to inbox, 20 seconds.
The 20 seconds is the worst I have seen, but it is not uncommon.
"Connection to server is slow" happens very often. If I use the server for 10 minutes, I will have seen it at least 5 times..
Apple Mail works a charm, as does all mobile devices. Sure, a bit more speed could be appreciated, but in general, it feels ok.
IOwait is around 10% constantly.
Total RAM: 98GB
Free RAM: 1.5GB (at the moment)
HP CPU: 2 x 4 core (avg 45% load)
zmcontrol-v: 8.7.11_GA_1854 FOSS Edition (It has been this slow since the day I started with Zimbra (7.something))
It is slow if I run it off Firefox local on the server also.
The above support company, myself and two other "consultants" have looked at the Zimbra Tune Server for Large Deployments (a link I have seen all over the internet).
I have made some changes there, and it at times makes a change, but, I feel that is more because I restart zimbra than anything else.
See, If I restart Zimbra, it tends to speed up a bit, nothing like google's webmail, but at least "reasonably" workable.
There is a constant lag, and the lag is so bad that people refuse to use it and set up their Apple Mail clients instead.
That is fine, but I have a large client that wants desperately to use it.
What else do you need to know to assist?
(you already have my eternal gratitude for having taken yourself the time to read this)
