I suspect someone had a specific case where Nagle's algorithm causes a real problem. They turn on TCP_NODELAY for that situation, see a huge improvement, and assume that it is a good idea to always turn on TCP_NODELAY. We had one case here were reloading a MOO database through a network connection took something like 5 hours. Turning on TCP_NODELAY reduced the time to about 10 minutes. We got all excited about that, and tried TCP_NODELAY in a number of other situations in the same MOO. In all other cases the option either hurt performance or did not help it enough to care about... -- Garance Alistair Drosehn = [EMAIL PROTECTED] Senior Systems Programmer or [EMAIL PROTECTED] Rensselaer Polytechnic Institute or [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
