The users are running Windows 7 SP1 with GW 12.0.2. Two users are experiencing slowness and sometimes crashing of their clients when going between folders. (i.e. between Inbox and Sent). This happens via webmail as well. There are 31 users on the Server Windows 2008 R2. Everyone connects via IP address as well.
It is Windows Server 2008 R2. It runs on 8 GBs of RAM. I have never seen it use more than 4 GBs. The CPU usage is not very high either.
The two users that are slow have mailboxes of over 10 GBs. I am not sure if that is relevant.
The client does stay idle while it processes from Inbox to Sent items or inbetween folders.
We just put in a gigabit switch since we thought that might be the issue. The POA isn't scanned by the AV. It has exceptions to both the PO folders and the Novell folder. It is a constant problem for those users so not an I/O.
