I have 2 Vmware hosts running ESX 4.1 build 348481. All of my vm guests are Server 2008 STD and ENT boxes. When I transfer files between them i get between 10-30 MB/s. Which is really low. All my guests connect at gigabit speeds and are running the Vmnet 3 driver. VMs are hooked to the same VSwitch. I know there are alot of people with the same issue, but I have been unable to find a fix.

Ive tried the following

Disable SMB2
Disable Auto Tuning.
Disable all offloads
Verified Duplex and Speed settings.
Uninstalled AV Product for testing
No firewall on guests.

Is it possible that an upgrade to ESXi5 , New VM Tools, could remedy this issue?
