    Default Under 100 users, 2.5GB RAM, 500mb Swap Space

    Greetings.
    I haven't upgraded to 6x yet and expect to quite soon.
    I'm a little hesitant as I'm experiencing swap use.
    Environment is virtual machine (Xen 5.5) running CentOS 5.3 (64bit)

    I have allocated ~2.5GB RAM and as you can see it's both used and going into swap for another 500MB.
    Mem: 2560000k total, 2504688k used, 55312k free, 92636k buffers
    Swap: 1052248k total, 525804k used, 526444k free, 331284k cached

    There are less than 100 users on this system and it's very lightly used at the moment. Do I really need to have 3GB+ RAM for this?

    I think if with about 100 users, it's too much ram to use. It's not good

    Im working on migrate all my email system (cyrus +SASL BerkeleyDB) into
    Zimbra 6 on a 2x Intel Quad-Core with 32GB RAM and 1 TB HD.

    it will have at least 10000 Mailboxes.

    I think i'll have 200-400 simultaneus sessions. I hope my system can hold
    all the work.

    CPU is OK, RAM is more than OK (8 or 16 GB should be enough) but I think you should go with RAID10 for the hardrives.

    I think my active sessions currently hovers around 10... I'm just adding more users so that'll change.
