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
