We have an optimized wrk here: https://github.com/sepherosa/wrk
I've glanced over your changes to wrk. (Btw, you have minor bug there: missed 'N' short flag in getopt_long() invocation for new --delay option, so "wrk --delay" works but "wrk -N" fails to parse command line.) I managed to reproducible get 4.38GB/s (about 36Gbps) with your version of wrk and it still eats over 60% of each core with "system time" using 8-core Intel(R) Xeon(R) CPU E5-2670 0 @ 2.60GHz. Same speed I get without your changes. I see that I cannot make even load for all four 10G ports of lagg interface and that's obvious reason to be unable to saturate 40Gbps. I need to create more connections for benchmark but then wrk eats even more CPU and overall throughput decreases. _______________________________________________ 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"
