Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Very cool. Thanks for doing a no-scan implementation of /dev/poll! Two questions: 1) have you compared its performance against Vitaly Luban's signal-per-fd patch? Even though it's realtime-signal based, there's some hope for it being quite efficient. See http://www.luban.org/GPL/gpl.html and http://boudicca.tux.org/hypermail/linux-kernel/2001week20/1353.html 2) A little birdie told me that someone had gotten a freebsd box to handle something like half a million connections. I would like to see you extend the horizontal axis of your graph by a couple orders of magnitude :-) Thanks, Dan p.s. I have updated http://www.kegel.com/c10k.html#nb./dev/poll with a link to your report. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
