Net Bandwidth testing

[tsitalon1]

Hey guys,

What utilities/tools are you using for internal cat5e network bandwidth testing?

I use Qcheck. It requires a PC at each end of the link to run the endpoint software, but is pretty handy for diagnosing throughput issues.

Netperf. It is a command line utility that does everything you need (TCP, UDP bandwidth, latency, connection open/close, reverse bandwdith, etc), runs just fine on an HD300, or any Windows/Linux/MacOSX PC. If you want binaries, PM me.

PS: A test of my HD300's bandwidth:

% netperf245 -H192.168.200.5
TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.200.5 (192.168.200.5) port 0 AF_INET

I've used JPerf - It requires Java JRE 1.5 or higher be installed to run, but it's very good.

I'd be interested in the netperf... can you send me a copy, please?
