    Default Performance problems 7.1.4 Virtualbox 4.1

    Good day,

    I'm new to the Zimbra world and I recently setup a Zimbra server in a smal company with 8 users.

    The reason we wanted to use Zimbra is they have couple of big mailboxes ( around 8-10gb)

    The setup we have is a physical server , 6 gb of ram, and
    AMD Athlon(tm) 64 X2 Dual Core Processor 5000+
     2.6 ghz
    The problem is that the server keeps filling the memory and it become unable to use it after couple of mins after reboot.

    out of free -m is :
                 total       used       free     shared    buffers     cached                                     
    Mem:          3523       3445         77          0         52       2202                                     
    -/+ buffers/cache:       1191       2332                                                                      
    Swap:         3814          0       3814
    I turned of swap cause it was starting to use that and turned of couple of serviced in zimbra we dont use, example: logger, stats

    The server went from 8.0 load to around 2 now

    Why is it so slow ?

    there come java processes that most of the process which is going on , other than that, the cpu seems to be in 20% and running okay,

    We are using outlook and thunderbird as imap clients

    each account has an external account which fetches mail from a pop server everyone 2 min

    please help

    I am running

    Release 7.1.4_GA_2555.F11_20120105094332 F11 FOSS

    In a VitrualBox 4.1.6 environment. I have only allocated 2.0G
    to the environment, run a tiny swap 200K. 5 users max,
    relative small mailboxes. Have used this setup since Zimbra 6 version.

    Clients were originally Outlook via IMAP. Now we are using the
    web interface 99% of the time.

    System runs stables eventually most of the memory is allocated but
    it doesn't seem to change performance. No errors.

    antispam Running
    ldap Running
    logger Running
    mailbox Running
    mta Running
    snmp Running
    spell Running
    stats Running
    zmconfigd Running

    Suggest trying to isolate the problems. What happens during start with no client access. How many inbound connections per minute etc.
    People will be able to better help if you can isolate where you
    think the problem is.
