I am running Zimbra on the following machine:
2 GB DDR2 667
3ware 8600 PCI SATA RAID (32-bit)
2x 80GB SATA (RAID 1)
Using Debian 4.0
Is there anything I can do to improve performance at all? The AJAX interface is sluggish (I know its client-side). There are approx 20 users maximum that would use it but usually 5 at the any one time.
