https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D263877 Bug ID: 263877 Summary: net/wireguard: go implementation is twice faster than the kernel's one Product: Ports & Packages Version: Latest Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: Individual Port(s) Assignee: decke@FreeBSD.org Reporter: lq@et-toile.com Flags: maintainer-feedback?(decke@FreeBSD.org) Assignee: decke@FreeBSD.org Dear Sirs, I am having better performance using the wireguard-go port than the wireguard-kmod port, I was expecting the opposite. I thought it was only related to my servers, so I tried on other servers (t= ried till now about 10 servers, using HP, Dell with igb/bge/cxl/ix) and still the same thing. Yesterday, I tried with a fresh installation on 2 servers and had the same results. So I am wondering if someone else is seeing the same problems. Here are some iperf3 on 2 fresh FreeBSD 13 both servers are Xeon E5-2640 128Gram: 1)Np VPN lro and tso on: [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 1.10 GBytes 9.41 Gbits/sec 0 1.61 MBytes=20= =20=20=20=20=20=20 [ 5] 1.00-2.00 sec 1.10 GBytes 9.41 Gbits/sec 0 1.61 MBytes=20= =20=20=20=20=20=20 [ 5] 2.00-3.00 sec 1.10 GBytes 9.42 Gbits/sec 0 1.61 MBytes=20= =20=20=20=20=20=20 [ 5] 3.00-4.00 sec 1.10 GBytes 9.41 Gbits/sec 0 1.61 MBytes=20= =20=20=20=20=20=20 [ 5] 4.00-5.00 sec 1.10 GBytes 9.42 Gbits/sec 0 1.61 MBytes=20= =20=20=20=20=20=20 [ 5] 5.00-6.00 sec 1.10 GBytes 9.42 Gbits/sec 0 1.61 MBytes=20= =20=20=20=20=20=20 [ 5] 6.00-7.00 sec 1.10 GBytes 9.41 Gbits/sec 0 1.61 MBytes=20= =20=20=20=20=20=20 [ 5] 7.00-8.00 sec 1.10 GBytes 9.42 Gbits/sec 0 1.61 MBytes=20= =20=20=20=20=20=20 [ 5] 8.00-9.00 sec 1.10 GBytes 9.41 Gbits/sec 0 1.61 MBytes=20= =20=20=20=20=20=20 [ 5] 9.00-10.00 sec 1.10 GBytes 9.41 Gbits/sec 0 1.61 MBytes=20= =20=20=20=20=20=20 - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 11.0 GBytes 9.41 Gbits/sec 0 sender [ 5] 0.00-10.00 sec 11.0 GBytes 9.41 Gbits/sec recei= ver 2)Np VPN lro and tso off: [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 518 MBytes 4.34 Gbits/sec 0 1.20 MBytes=20= =20=20=20=20=20=20 [ 5] 1.00-2.00 sec 543 MBytes 4.56 Gbits/sec 0 1.61 MBytes=20= =20=20=20=20=20=20 [ 5] 2.00-3.00 sec 542 MBytes 4.54 Gbits/sec 0 1.61 MBytes=20= =20=20=20=20=20=20 [ 5] 3.00-4.00 sec 537 MBytes 4.51 Gbits/sec 0 1.61 MBytes=20= =20=20=20=20=20=20 [ 5] 4.00-5.00 sec 536 MBytes 4.50 Gbits/sec 0 1.61 MBytes=20= =20=20=20=20=20=20 [ 5] 5.00-6.00 sec 533 MBytes 4.47 Gbits/sec 0 1.61 MBytes=20= =20=20=20=20=20=20 [ 5] 6.00-7.00 sec 533 MBytes 4.47 Gbits/sec 0 1.61 MBytes=20= =20=20=20=20=20=20 [ 5] 7.00-8.00 sec 537 MBytes 4.50 Gbits/sec 0 1.61 MBytes=20= =20=20=20=20=20=20 [ 5] 8.00-9.00 sec 539 MBytes 4.53 Gbits/sec 0 1.61 MBytes=20= =20=20=20=20=20=20 [ 5] 9.00-10.00 sec 540 MBytes 4.52 Gbits/sec 0 1.61 MBytes=20= =20=20=20=20=20=20 - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 5.23 GBytes 4.49 Gbits/sec 0 sender [ 5] 0.00-10.03 sec 5.23 GBytes 4.48 Gbits/sec recei= ver 3)Wireguard-go: [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.01 sec 100 MBytes 832 Mbits/sec 307 383 KBytes=20= =20=20=20=20=20=20 [ 5] 1.01-2.00 sec 23.0 MBytes 194 Mbits/sec 337 983 KBytes=20= =20=20=20=20=20=20 [ 5] 2.00-3.00 sec 65.8 MBytes 553 Mbits/sec 530 41.4 KBytes=20= =20=20=20=20=20=20 [ 5] 3.00-4.00 sec 89.8 MBytes 753 Mbits/sec 411 98.1 KBytes=20= =20=20=20=20=20=20 [ 5] 4.00-5.01 sec 99.9 MBytes 830 Mbits/sec 337 1.14 MBytes=20= =20=20=20=20=20=20 [ 5] 5.01-6.00 sec 24.5 MBytes 207 Mbits/sec 651 2.67 KBytes=20= =20=20=20=20=20=20 [ 5] 6.00-7.00 sec 90.6 MBytes 762 Mbits/sec 472 79.1 KBytes=20= =20=20=20=20=20=20 [ 5] 7.00-8.00 sec 88.6 MBytes 744 Mbits/sec 387 152 KBytes=20= =20=20=20=20=20=20 [ 5] 8.00-9.01 sec 40.9 MBytes 339 Mbits/sec 791 1.35 MBytes=20= =20=20=20=20=20=20 [ 5] 9.01-10.00 sec 81.3 MBytes 691 Mbits/sec 1423 91.2 KBytes=20= =20=20=20=20=20=20 - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 705 MBytes 591 Mbits/sec 5646 send= er [ 5] 0.00-10.00 sec 703 MBytes 590 Mbits/sec recei= ver 4)Wireguard-kmod: [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 39.5 MBytes 331 Mbits/sec 0 485 KBytes=20= =20=20=20=20=20=20 [ 5] 1.00-2.00 sec 39.0 MBytes 327 Mbits/sec 0 490 KBytes=20= =20=20=20=20=20=20 [ 5] 2.00-3.00 sec 39.0 MBytes 327 Mbits/sec 0 490 KBytes=20= =20=20=20=20=20=20 [ 5] 3.00-4.00 sec 39.0 MBytes 327 Mbits/sec 0 490 KBytes=20= =20=20=20=20=20=20 [ 5] 4.00-5.00 sec 39.0 MBytes 327 Mbits/sec 0 490 KBytes=20= =20=20=20=20=20=20 [ 5] 5.00-6.00 sec 39.0 MBytes 328 Mbits/sec 0 490 KBytes=20= =20=20=20=20=20=20 [ 5] 6.00-7.00 sec 39.1 MBytes 327 Mbits/sec 0 490 KBytes=20= =20=20=20=20=20=20 [ 5] 7.00-8.00 sec 39.1 MBytes 329 Mbits/sec 0 490 KBytes=20= =20=20=20=20=20=20 [ 5] 8.00-9.00 sec 39.1 MBytes 328 Mbits/sec 0 490 KBytes=20= =20=20=20=20=20=20 [ 5] 9.00-10.00 sec 39.1 MBytes 328 Mbits/sec 0 490 KBytes=20= =20=20=20=20=20=20 - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 391 MBytes 328 Mbits/sec 0 sender [ 5] 0.00-10.02 sec 391 MBytes 327 Mbits/sec recei= ver Thank you for any suggestion to debug this issue.
