    Unhappy Slow zimbra questions

    Hi All,

    I was wondering if you could tell me why my zimbra seems to be sooo slow? I have currently setup 2 dev zimbra servers one as an active mailstore and one as standby which does not have a MX record in DNS yet. I also have them querying another zimbra ldap server. I have no accounts loaded yet.

    The servers are virtual machines with dual core 2.8 cpus and over 4 gig of memory. the servers attach to a netapp filer for storage and everything seems to be behaving normally except zimbra. I also have a alot of other vm's accesssing the filer in the same way and they are very fast!

    When i perform a zmcontrol start it takes about 3 minutes to finish executing. The actual load on cpu continues to jump up and down from 10% - 80% every couple of seconds. Memory is no where near at maximum capacity.

    I am concerned since zimbra is supposed to offer good redundancy but i cant see how this could be possible if it takes over 3 minutes to have the standby server take over.

    Even when i call basic commands such as zmcontrol status it has a delay of about 5 seconds.

    Does anyone have any suggestions. I read that somewhere that this behavior is normal but surely not?????

    Which operating system are you using for Zimbra? How much RAM does the VM have? Which virtualisation product are you using?
