"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

FTP or RoboCopy. Robocopy is part of Win2k tools in Resource Kit.
FTP gives you throughput metrics at end of each transfer.

"Netcps is a handy utility to measure the effectice performance on a TCP/IP network.

I wrote it during a trouble shooting session with some cisco switches that seemed to have problems with 100mbits connections. I was bit surprised when I failed to find any such utilities on the net...

Start "netcps -s" on one machine, and "netcps ip.address.to.other.machine" on the other machine, and the two programs will pump 100 MB of data over the network. The CPS is measured with 1/1000 second's accuracy.

Note that winsock seems to take quite some CPU resources on high-speed connections. I got ~4 MB/s max on a Intel Pentium 133, and ~7 MB/s on an AMD K6 200, using a Intel Pentium Pro 200 server with NT 4.0 Server as the other host. I got a report that two Pentium 200 servers running NT 4.0 server had 10 MB/s on a direct connection (server to server, no hub or switch).

Netcps use a normal TCP/IP connection, pumping data without any disk access. The source code is attached.

Netcps was something I wrote in a hurry. It should be useful for testing networks, and the performance of hubs, switches and routers. The program is targeted towards my needs, and has no fancy features. The program should however be useful for network professionals. It's quite small and easy to use :-)"
