Testing methodology?

[ashG]

I have an Intel 10/100/1000 PCI-E NIC on the way to replace my desktop's built-in Realtek 8111b. I want to see how much of a difference there really is between the two.

Any recommendations?

Iperf is usually the preferred method. You run it on one computer in server mode. (Iperf -s) Then you run it on another machine using the IP address of the server as the computer to connect to. So generally I use a command line like... iperf -c 192.168.0.2 -w 64k -r. The -w sets the window size and -r is to test in both directions.

iperf and ixChariot are excellent tools to test throughput.

However, in this case, you want to test the performance of the PCI-E Intel NIC.
There are still many variables that affects the test results.

1. CPU of the computer the Intel NIC is installed.
2. PCI-E bus speed of the PCs motherboard.
3. The NIC and specs of the other computer.

The point is, are you testing the Intel NIC, or testing the whole setup
