The mail server is now replaced and upgraded but things will be somewhat slow still for a couple of days.

     Two things, one it is on a RAID but the RAID hasn’t had time to sync all the disks before I put it in service, it is still doing that.

     Two is that I’m still moving virtual machines around and disk I/O is becoming fast enough that it can saturate a gigabit interface.  So between these two things it will be somewhat slower than optimal for a few more days but should be better than what it was.
