    Default installation and server really slow?

    I've got a pretty fast computer, with 4G of ram. (Running Ubuntu 6.06 by the way)

    For some reason my install just crawls. The packages load and such just fine, but some parts of the installation, such as installing skins and starting servers take ages. I can expect to wait several minutes for each step.

    Running /etc/init.d/zimbra start or stop also takes an exceeding long time.

    I've tried uninstalling and reinstalling to no avail.

    Do others find Zimbra this slow?

    Michael

    Update: I've just tried to install this under Ubuntu 6.10 running under vmware on my system. It is quite a bit faster than on the native host itself. (in other words, Zimbra under vmware is faster than zimbra on the native host itself.) Could this be because I am running sun's java on the native host, and using gij on the vmware system?

    I too have been amazed at how slow it is. I have it installed on an IBM X336 server with a 3GHz Xeon processor, 4GB RAM, 300MB 10KRPM SCSI RAID1. OS is Linux CentOS 4.4.

    I agree, /etc/init.d/zimbra stop / start seems like it takes a long time, and logging in either to the admin account or a user takes a long time. After getting logged in it seems pretty OK, but overall the performance is pretty doggy compared to most other apps on this same hardware (we have 20 of these servers).

    As the Zimbra installation is just in eval mode here I haven't really had the time or inclination to figure out why it's so slow, but it's sure going to enter into the decision as to whether or not to take it into production.

    mailhost:/root# time /etc/init.d/zimbra restart

    real 0m43.517s
    user 0m9.843s
    sys 0m2.742s

    Check id you're not hitting the "unicode start" bug.

    See this post : Post install : Zimbra start up is taking upwards of 10 minutes and the wiki.

    I should say the start / stop time isn't that big an issue, since it normally would only happen during boot and the server won't get booted that often. But 20 seconds for a user to log in seems like there are some improvements to be had somewhere. If you change the theme and want it to use it now, that takes 20 seconds too.

    I changed /etc/syconfig/i18n per the wiki and rebooted the server because I don't know when that stuff gets read. No difference. Well, almost no difference:

    mailhost:/root# time /etc/init.d/zimbra restart

    real 0m40.697s
    user 0m9.154s
    sys 0m2.636s

    Still takes 20 seconds to log in or change themes, too.

    Although now I see that Zimbra comes with its own java interpreter, so it can't be that.
