Hello,
I am trying to do some experiments using iperf, but there are some
characteristics that are not clear to me in the documentation and not even
in the source code.
First regarding the time interval lower bound. Is there any reason to limit
the time interval to 0.5s? Or could I just do the same as the author of this
patch (
https://www.hep.manchester.ac.uk/u/stevek/code/diff-iperf-2.0.2-interval-limit.txt)
and comment out this parameter constraint? I would like to use intervals in
the order of milliseconds.
Also regarding the TCP window size. What exactly happens when I set the
window size in a modern linux (which should have auto-tunning)? Should I
expect the size to change or to be hard limited by the rule? Also, in iperf3
when you set the window size it uses setsockopt in both SO_SNDBUF and
SO_RECVBUF
while iperf2 I think that only sets one of them dependending if it is a
server or a client. Why is that so and what are the consequences of this?
