https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D282095 Zhenlei Huang <zlei@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |zlei@FreeBSD.org --- Comment #1 from Zhenlei Huang <zlei@FreeBSD.org> --- I have a two ports Chelsio T520-CR card. With the default MTU 1500, either = TCP or UDP mode iperf3 can easily reach ~9.6Gbps. For UDP the loss rate is also negligible. I think only ~3.7Gb/s for a 10G nic with default MTU 1500 is not reasonable. Well the enic(4) driver was introduced on Feb 6 2023. That is quite new. I moved cxl1 to a separated vnet while doing the benchmark. For multiple fi= bs setup, the result is similar. ``` # jail -ic vnet persist 1 # ifconfig cxl1 vnet 1 # jexec 1 ifconfig cxl1 inet 192.168.99.1/31 # jexec 1 iperf3 -sD # ifconfig cxl0 inet 192.168.99.0/31 # iperf3 -ub0 -c 192.168.99.1 Connecting to host 192.168.99.1, port 5201 [ 5] local 192.168.99.0 port 19631 connected to 192.168.99.1 port 5201 [ ID] Interval Transfer Bitrate Total Datagrams [ 5] 0.00-1.00 sec 1.11 GBytes 9.56 Gbits/sec 819173=20=20 [ 5] 1.00-2.00 sec 1.11 GBytes 9.57 Gbits/sec 819938=20=20 [ 5] 2.00-3.00 sec 1.11 GBytes 9.57 Gbits/sec 819165=20=20 [ 5] 3.00-4.00 sec 1.11 GBytes 9.57 Gbits/sec 819298=20=20 [ 5] 4.00-5.00 sec 1.11 GBytes 9.57 Gbits/sec 819118=20=20 [ 5] 5.00-6.00 sec 1.11 GBytes 9.57 Gbits/sec 818958=20=20 [ 5] 6.00-7.00 sec 1.11 GBytes 9.56 Gbits/sec 818553=20=20 [ 5] 7.00-8.00 sec 1.11 GBytes 9.57 Gbits/sec 819750=20=20 [ 5] 8.00-9.00 sec 1.11 GBytes 9.56 Gbits/sec 818532=20=20 [ 5] 9.00-10.00 sec 1.11 GBytes 9.58 Gbits/sec 819819=20=20 - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate Jitter Lost/Total Datagrams [ 5] 0.00-10.00 sec 11.1 GBytes 9.57 Gbits/sec 0.000 ms 0/8192304 (= 0%)=20 sender [ 5] 0.00-10.00 sec 11.1 GBytes 9.56 Gbits/sec 0.000 ms 743/8189808 (0.0091%) receiver ``` --=20 You are receiving this mail because: You are the assignee for the bug.=
