increase network utilization w/ crossover

June 2, 2009 at 15:42:05
Specs: Windows 2003

I have two PCs (w/ gigabit adapters)
connected via crossover cable. Each PC has a
static IP address and the same subnet mask.
No gateway nor DNS. I am trying to transfer
large files (avg. 2 Gb) over from one PC to the
other. The first 5-8 seconds I get network
utilization of about 20-30% but after that it
crashses to 0-1%. Is there any network or
adapter configurations I can change to make
the connection consistent?

Not really. About the only thing you can do is check the NIC's on both PC's and ensure the speed is set to "auto" and then check to see what they're connecting at.

If they're connecting at 1 GB, then everything is fine. As far as network utilization goes, at 1 GB, 1% is a whole lot more than 1% of 100 or 10 Mbps.

How long is it taking to transfer the 2 GB's of data?

Thanks for replying. On average it took us 10-15 minutes for a
2Gb file.

Network utilization is showing you that the network is not the bottleneck. It is what is happening before the nic transfer and after delivery to the distination nic that is the bottleneck.

10 to 15 min's is way too slow for a smaller 2 GB transfer.

I'd have to agree with wanderer. If the NIC's are both connecting at 1 GB, the only answer can be the other side of the network interface (ie: the computer side).
