Thanks, Josh. I started testing vmxnet3 last week, but I didn't know I could set the mtu level. I found this info, so I'll test it out.
Can you point me to a guide for vmxnet3 settings and recommendations? I've only been able to find a few things piecemeal.
The san is only Gb, so no reason to go to a 10 gb switch for now. However, switching all vm nics to vmxnet3 will probably allow us to forget about the switch upgrade for awhile.
Backups are running at night and most terminal server work is being done during the day. Tripling the backup speed helped us avoid backing up during work hours.
Thanks again.
