i too am currently looking into natd - it seems to eat more cpu as the number of connections it handles goes uip - not just the throughput. - i'm not an expert but truss, strace and grof show that most of the time is spent in sendto() ... ... i find this odd becuase recvfrom seems not to be so intensive. ps - can anyone tell me if the following assumption is correct: * if gprof, strace, etc show most of the time spent in sendto() then it immediately follows that this is what is using CPU time? * i know its a bit off topic but i could make a syscall which simpy sleeps, so shows up as taking time but isn;t doing much really? am i right? intY has automatically scanned this email with Sophos Anti-Virus (www.inty.com) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
