Hi newbie here but been using pCP for years. Thank you for the great work.
Redo'ing my home network these days and when testing the speed I saw, strangely, the result of iperf3 from pCP's interface diff than that of running directly from command line. I'm on a gigabit network direct wired connection. Output from pCP's UI, after 20sec. > [ WARN ] Squeezelite is running, results might be affected > [ WARN ] Goto Main menu and stop squeezelite > [ INFO ] Iperf running in TCP Mode. > [ INFO ] Iperf running in Receive Mode. > [ INFO ] Iperf will run for 20 seconds, then output will show....... > iperf 3.6 > Linux pCP-LivingRm 5.4.83-pcpCore-v7l #1 SMP Fri Dec 18 23:03:44 EST > 2020 armv7l > Control connection MSS 1448 > Time: Tue, 15 Jun 2021 15:42:56 GMT > Connecting to host 192.168.8.12, port 5201 > Reverse mode, remote host 192.168.8.12 is sending > Cookie: qygclmqlekstboxbjl6mtg4yz7cpt2txqrti > TCP MSS: 1448 (default) > [ 5] local 192.168.8.31 port 33610 connected to 192.168.8.12 port 5201 > Starting Test: protocol: TCP, 1 streams, 131072 byte blocks, omitting 0 > seconds, 20 second test, tos 0 > [ ID] Interval Transfer Bitrate > [ 5] 0.00-1.00 sec 33.1 MBytes 277 Mbits/sec > [ 5] 1.00-2.00 sec 35.8 MBytes 300 Mbits/sec > [ 5] 2.00-3.00 sec 35.8 MBytes 300 Mbits/sec > [ 5] 3.00-4.00 sec 35.7 MBytes 300 Mbits/sec > [ 5] 4.00-5.00 sec 35.8 MBytes 300 Mbits/sec > .... > [ 5] 17.00-18.00 sec 35.8 MBytes 300 Mbits/sec > [ 5] 18.00-19.00 sec 35.7 MBytes 300 Mbits/sec > [ 5] 19.00-20.00 sec 35.9 MBytes 301 Mbits/sec > - - - - - - - - - - - - - - - - - - - - - - - - - > Test Complete.
