It is rc1 - and crashes. I test on i386 via epia (the only machine which runs x86 right now). If there will not be any new patches, I will create 2.6.20 test tree tomorrow. > if you create a threadlet based test-webserver, could you please do a > comparable kevents implementation as well?

But note, that on my athlon64 3500 test machine kevent is about 7900 requests per second compared to 4000+ epoll, so expect a challenge. lighhtpd is about the same 4000 requests per second though, since it can not be easily optimized for kevents. > Ingo -- Evgeniy Polyakov - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
