[snip] ok, so this is what I was seeing when I was working on this stuff last.
The big abusers are: * so_snd lock, for TX'ing producer/consumer socket data * tcp stack pcb locking (which rss tries to work around, but it again doesn't help producer/consumer locking, only multiple sockets) * for some of the workloads, the scheduler spinlocks are pretty heavily contended and that's likely worth digging into. Thanks! I'll go try this on a couple of boxes I have with intel/chelsio 40g hardware in it and see if I can reproduce it. (My test boxes have the 40g NICs in NUMA domain 1...) -adrian _______________________________________________ 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"
