I got almost 20gb / s added, Below is a video of a presentation of mine showing the case.
Dell r410, Intel X520-da2, https://youtu.be/8DdtN_fj_uQ De: Lyubomir Yotov <l.yo...@gmail.com> Enviada em: quarta-feira, 22 de janeiro de 2020 09:05 Para: bsdrp-users@lists.sourceforge.net Assunto: [Bsdrp-users] 10Gbps interface performance with BSDRP Dear Olivier, All the best for the New 2020! In the last few weeks I did some tests with a colleague (a Linux guy) about 10Gbps performance and BSDRP. The test was between two servers with connected through a switch. I use Chelsio T520-CR on two HP DL360 with dual Xeon E5520@2,27GHz. I was a bit surprised that we couldn't get more than ~3.8Gbps-4.0Bgps with iperf (iperf2 and iperf3 single flow, multiple flows...), both BSDRP v. 1.96 and stock FreeBSD 12.0. We did the same tests (BSDRP v. 19.6 only) on two directly connected Dell R610 with X5670@2.90GHz <mailto:X5670@2.90GHz> with the same success. At the same time with a Proxmox I can get ~7Gbps, which seems a reasonable result. When using the netmap userland tools I can see that ~14Mpps are going to the switch. So it is not CPU bound IMHO. I searched for tunings on the web but what I found was already set in BSDRP. Any help would be appreciated as I intend to use the cards in production but the current performance is not satisfactory. Regards, Lyubo
