Since I virtualized my mail server it's so freaking slow. I think it's disk I/O between VM server and NAS. That's always been my big bottleneck. NFS is just slow. Need to look at switching to iSCSI but that's more complicated especially once I start adding more hosts which I eventually want to do. What I'd like to see is if I can get VMs to use an iSCSI lun directly as drive, it would skip a couple layers of complexity and be faster. Would need to make 1 lun per VM but that would be doable if I can easily automate it. Eventually want to get off VMware, that was just a temp thing as it's super turn key. The Linux solutions are more advanced but more tedius to use without writing some kind of front end.
