is there a tcp window size restriction?
I just noticed that I can't get a 1MB tcp window on debian 11
$ iperf --version
iperf version 2.1.4 (18 August 2021) pthreads
$ iperf -s -w 1M --time 60 -i 10
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 416 KByte (WARNING: requested 1.00 MByte)
The exact same software (.. or at least the same source code) on a
windows 10/cygwin machine says I get the full 1MB tcp window size:
TCP window size: 1.00 MByte
So is there something on the Debian machine limiting the tcp window &
if so, how do I change it.
Thanks
Lee
