    How many CPU on the host, how many RAM, etc ?

    If the VM freezes (with vmware tools setup), I think you'll get more information on the vmware communities forum...

    My host server running with 2cpu's (3GHz) Intel Xeon with 4gb ram and 750Gb hdd.ubuntu 8.04LTS server with zimbra 5.0.9 is running as a virtual host on vmware with one virtual processor.There's no problem while running with one virtual processor but zimbra clients takes a very long time to login to their account.when I change the processor to 2 virtual processors then the freezing occurs,I have to manually stop the vm and restart again.so could you help me with why the zimbra clients takes a very long time to login to their acc..both from local and from outside.

    The host RAM is irrelevant, how much RAM is allocated to the Zimbra VM?

    BTW, you should never change the number of CPUs allocated to a virtual machine once you've created it. It can cause problems such as the one you're experiencing.

    I would certainly not allocate both CPUs to the VM unless they are dual/quad core. As Phoenix has said what is the VM memory allocation as that will be where performance is gained.

    I have dedicated 2Gb RAM out of 4 to zimbra mail server...Indeed I have the option of selecting 1,2 and 4 virtual processors in the vmware.when using one virtual processor there's no hanging but zimbra response is very slow ..the web mail users takes a very long time to login to their accounts both within the LAN and from outside..the server I''m using is Dual core ...so can you please help me on why the zimbra login response is very slow(takes around 3-4min to login)...previously after the fresh install of zimbra the login time was very quick..but after adding around 30 accounts..the zimbra login response started to get very slow..was it because of the acc overhead???...please guide me...

    Does this happen with both the standard HTML client and the Ajax one ? If standard is okay then this would point to the performance of the clients as Ajax does take additional client side processing. How many clients are connecting ?
