Sure, that's why I asked. I see the fgets stuff looking lock contend-y, and I see a sleeplock kicking in via kern_sendit -> sx_xlock_hard; so something's blocking on a lock. The kqueue locking too is a problem - kqueue doesn't handle lots of fast producer/consumer things and it contends badly. :( -a > > > > ---- On Thu, 21 Jan 2016 14:11:34 -0800 Adrian Chadd > <[email protected]> wrote ---- > > Well, how many interrupts/second is this seeing? > > > > > > -a > > _______________________________________________ > > [email protected] mailing list > > https://lists.freebsd.org/mailman/listinfo/freebsd-transport > > To unsubscribe, send any mail to > "[email protected]" > > > _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-transport To unsubscribe, send any mail to "[email protected]"
