https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D225179 Olivier Cochard <olivier@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |olivier@freebsd.org Version|12.2-RELEASE |CURRENT --- Comment #5 from Olivier Cochard <olivier@freebsd.org> --- Reproduced on FreeBSD 15.0-CURRENT #45 main-n271697-9ff2ebd92891-dirty. With a cross-over cable, iperf3 in TCP mode wasn=E2=80=99t able to reach 40= 0mb/s (due to very busy drivers not able to process all input ACK from the server). switch to UDP mode, the client was able to reach 900mb/s, but the server reported only half of it (50% loss). Then tested the magic command "mediaopt flow": root@mobile:~ # ifconfig -v ue0 | grep media media: Ethernet autoselect (1000baseT <full-duplex>) root@mobile:~ # ifconfig ue0 mediaopt flow root@mobile:~ # ifconfig -v ue0 | grep media=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20 media: Ethernet autoselect <flowcontrol> (1000baseT <full-duplex,flowcontrol,master,rxpause,txpause>) And no more performance problem (all driver functions diseapear from a flamegraph), it reach 909 Mbits/sec in client TCP mode. --=20 You are receiving this mail because: You are the assignee for the bug.=
