    Default Free T-Shirts. Just for fun.

    Reading the posts in this thread got me thinking...

    http://www.zimbra.com/forums/administrators/2253-what-hardware-does-your-zimbra-system-runs-post13901.html

    I'll send a shirt to those who can provide the best user to CPU and user to MEM ratio.

    Calculate for your system like...

    CPU (Hz) / Active Users ==> 1600 Hz / 25 Users = 64 Hz/User

    MEM (MB) / Active Users ==> 2048 MB / 25 Users = 81.92 MB/User

    Since this works against those with big systems or large user bases I'll give two more shirts for most active user's and largest system defined as CPU (Hz) + RAM (MB).

    Well, I'll start

    CPU: 80Hz / User
    RAM: 81.92 MB / User

    That's based on counting two 1Ghz processors as being 2G, which is not quite true, so a more conservative 1.5Gz would give 60 Hz / User.

    Then there's my home machine, which comes in at 550Mhz / User and 256Mb / User. But then it's only supporting two people !

    I can beat this one
    MEM 2 GB/User
    CPU 2*2GHz/User (Centrino Duo)
    the point is its just one user
    so maybe this doesnt count, does it?
    Regards and thanks for your good work

    Default

    500MHZ / 11 active users = 45.46MHz/user

    512MB / 11 active users = 46.55MB/user

    Yes, it is upgrade time.......

    Default as a xen VM...

    1149 users in a xen VM, on top of a 3.0 Ghz (single core) Xeon (1MB cache) processor (with HW raid to take care of I/O). 2731984k of memory allocated to that VM. THe vast majority only uses the web UI.

    3Ghz/1149 =2,61 MHz/user
    2,668GB/1149 = 2,322MB /user

    The box will soon be upgraded to a dual dual core SUN 4100 box, with a SAN backend.

    Default

    Here goes:

    3.0GHz * 2 Xeons
    3.0GB RAM
    106 users currently

    6000MHz / 106 = 56.60Mhz / user
    3000MB / 106 = 28.3 MB / user

    Here's one more: all these users connect on a 768k (for now) uplink:
    768 kbytes/sec / 106 = 7.25 bytes per second per user

    Default Mine

    I'm running Zimbra 3.14 on a Sun X2100 with 2GB RAM. I'm running on a VMWare session, and only dedicated 1252MB to Zimbra

    AMD Dual Core 'Processor 180' shows up as 2.41Ghz each

    I'd be generous in counting 10 active users (it's a home email server, and only 8 are active)

    CPU (Hz) / Active Users ==> 4820 MHz / 10 Users = 482 MHz/User (241Mhz/user if you only count 1 core)

    MEM (MB) / Active Users ==> 1252 MB / 10 Users = 125.2 MB/User

    Default Not going to win the contest but ..........

    Great timing i just upgraded my machine from a 2Ghz celron and 512Mb RAM with such a small amount of RAM Zimbra was really slow and unstable. As of last thursday i have a P4 3.2 Ghz and 2.5G of RAM Zimbra is really Rock Solid now and very quick too.

    Intel p4 3.2Ghz / 15 Active users is 213 Mhz / User
    2.5 GB Kingston RAM / 15 Active users is 167 GB per user

    Default Ok... I'll try

    I'm running a system here with dual 450 (P2?) and 1GB ram for 42 users (thankfully they don't all use it at the same time ... customer service). Oh, and it is a bit sluggish.

    450 X 2 / 42 = 21.4 MHz/User
    1024 / 42 = 24.4 MB/User

    Oh, anything for a free t-shirt...

    I'm running two seperate systems:

    System 1:

    RAM: 3GB / 10 users = 307.2
    CPU: 2.2Ghz * 2 / 10 users = 440

    System 2:

    RAM: 2GB / 184 users = 11.13
    CPU: 2.4Ghz / 184 users = 13.03
