As a followup to my TTCP blog entry, here is a list of a few other network throughput testing tools:
- iperf 3 on github, was on google code.
- iperf: windows binaries
- ttcp: code for ttcp , nttcp
- nuttcp
I have been using iperf for testing various connections. Single direction testing usually yields good results. When using iperf client / server in one direction on a bidirectional ntework on port 5001, and another iperf client / server in the other direction on port 5002, I get asymmetrical bandwidth reports. More testing is needed to determine if this is a network problem, a host problem, or an application problem.
