Zimbra slow in very small deployment

[infernalshade]

Maybe you're right, but Zimbra 5.x and Ubuntu 8.04 is working very well on our VirtualBox, so why should i switch to another VM?

EDIT:
Also, the prices for VMware ESX starting at $1,068.00... That's no solution/option in our case..

I didn't say it wouldn't work I said it wasn't supported and isn't recommended for production environments. This is an open source project and you can, of course, run it in any environment you like.

VMware ESXi is free as is XEN Server, their performance and management functions are far better than the current virtualisation options inside your operating system.

Well in the worst case the VM Crashes...then i'll reboot it and all is fine, if not, then i'll take a backup. We aren't a "big" company, so this is a good solution for us, maybe we can switch to a "real virtualized" Server some time, but not now.

Same here.
Personally, I don't know if I would qualify a 5 user install as a production installation. I'm pretty sure people are doing bigger install just for testing. This is probably a perfect candidate for a hosted solution if it wasn't for the size of our accounts. Thing is, it works beautifully after reboot, it only degrades with time.
I will probably give it a try converting it to virtualbox this weekend.

Are you running your server constantly with a snapshot? That'll kill performance as well..

[alberto]

No, I just take one at midnight for the backup process and I take it back afterwards.

Hmm ok. Just thought I'd throw that out there just in case.

Zimbra on Virtualbox? On which hardware does this setup running?
I've installed Ubuntu/Zimbra on Virtualbox and it takes over ten minutes to start...

[infernalshade]

We're running Virtualbox on a Core2Quad | 4GB DDR2 Machine.
We assigned about 1GB-1,5GB to the VM.
We are using Ubuntu 8.04 LTS with ZCS 5.0.16 Open Source Edition installed.

Ubuntu takes about 1 Minute to start on our system!
When Ubuntu is started, then zimbra takes also 1 Minute to start, and i think every "real" Server wouldn't Start such a System that fast..

I too am running a small (~10 users) installation. However ours is deployed in ESXi and I am experiencing the same issue. I am also running Ubuntu 8.04 LTS Server. Exact same problem in our installation. It runs great after reboot and a couple days later CPU reaches upwards of 75-90%. When we perform a top it is a "Java" process that is pegging the CPU.

Initially I tried just restarting the zimbra server without rebooting. When I did this the problem remained and strangely even when the zimbra server was stopped the Java process remained. Rebooting the server fixes it for a few more days.

The server is ubuntu 8.04 LTS running in a 32-bit VM (Paravirtualized) with no applications on it other than Zimbra. We have allocated 2 vCPU's and 2G of memory. I am thinking that maybe the java version doesn't play nice with ubuntu. I may try and move it to CentOS or Red Hat to see if it fixes the issue.

Have you been able to make any progress on this? Any chance you can check and see if the CPU hog on your box is Java and if it remains after stopping the zimbra server?
