I have two Dell Servers with multiple gigabit network ports each. These run a sync process using XCOPY. To improve throughput and reduce overall network impact, I have dedicated a connection on each machine to this purpose by directly connecting the machines with a cat 6 crossover cable and setting static IP addresses that are completely off the standard network. The transfer is mainly a one-way process.

The source machine is a VM with a separate virtual adapter configured to directly use the specific adapter on the host.

I am seeing only 50-60% network utilization of the adapters on the two machines. I would expect to see greater than this with setup. Any suggestions?

try robocopy /MT for more efficient network utilization. – Andrey Voitenkov Feb 20 '13 at 7:34
Obviously the network connection is not the bottleneck. Have you checked the disk I/O and CPU utilization while the transfer is taking place? – wookie919 Feb 20 '13 at 23:50
