VM nic performance issue...again

Hi all.

Esx 3.5 Update 1

Windows 2003 R2 SP2 Enterprise

When copying from 2 vm's on the same host i get about 45% of the 1Gbit link.

When I migrate it to a different host i get about 20%.

Now here is the weird thing. When I migrate it back to the same host (both now on the same host), I still get about 20%.

However, when I disable and enable the nic, I get about 45% again.

Any idea why this is happening? Using Enhanced driver on both Windows machines with no AV installed. Clean servers.
