Hi there, I can't but remind you that there's polling(4) in FreeBSD :-)
Until today, I was convinced for some obscure reason that polling(4) was an experimental feature that might or might not work. Today I tried it on our central router box and got astounding results. The router box is a 1.4GHz Celeron PC with an fxp(4) interface split across a dozen of vlans. There is nothing special about its setup except for ~250 rules loaded into ipfw2. It is running 4.10-RELEASE. Without polling, it was able to switch full 10Mbytes/sec of traffic (~9kpps), but that took from 50 to 70% CPU time spent in interrupts. With polling on, interrupt time never exceeds 5% and it stays as low as 1-2% on average even when traffic is that high. Many thanks to folks who have had a hand in polling(4) development! Just in case: Please be aware that polling(4) won't make KDE run faster unless on a busy router ;-) -- Yar _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
