[Iperf-users] iperf tests with many connections

[Damian L. <Dam...@ri...>]

Hi,

I've observed that using many connections (hundreds) with iperf (-P 100 for example) has some issues:
- In links with some latency it takes forever to start testing. This time seems to grow much faster than linear. For example 20 secs for 50 connections and 100 secs for 100 connections.
- At some point between 100 and 200 connections, iperf stops showing the [SUM] row at the end with the total result

Any ideas?

(the iperf version I have available in this environment is quite old 2.0.4, should I expect this to be fixed in a newer version?)

Thanks,
Damian
