A quick and dirty workaround is to "cpuset" iperf and the interrupt and > taskqueue threads to specific CPU cores. My CPUs : 2x E5-2620v3 with DDR4@1866. What is strange is that even without using the card (iPerf on localhost), as my results show, I have very low and unstable random throughput (compared to Linux on the same host). > Are you using "options RSS" and "options PCBGROUP" in your kernel config? I only installed FreeBSD 10.3 and updated it, so I use the GENERIC kernel. RSS and PCBGROUP are not defined in /usr/src/sys/amd64/conf/GENERIC, so I think I do not use them. > Are you also testing CX-4 cards from Mellanox? No, I only have CX-3 at my disposal :) Ben PS : in my previous mail I sometimes used GB/s, of course you must read Gb/s everywhere. _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
