Oh, good idea :o) We are using w2k and i just now checked the maximum packetsize my machine was able to transfer without fragmentation (ping -f -l [packetsize]). It seems to be 1472 regardless of destination (localhost or ip of the host). But of course you are right, its unnecessary to busy the whole network drivers layers.
Okay... i'm now going to check out all our machines if there is anywhere an IP instead of localhost (we have some troublemaker... may this resolves their problems) Thank you for explanation :o) Ilona -----Ursprüngliche Nachricht----- Von: Halstead, Chris [mailto:[EMAIL PROTECTED] Gesendet: Dienstag, 22.

The MTU over loopback (127.0.0.1) is on the order of 8k in Solaris and 16k in current Linux distros, whereas the MTU over a real IP maxes at 1500. The larger MTU will prevent fragmentation of your responses into multiple packets. Using loopback should also avoid going up and then back down the network driver layers. If all your communication is local, use localhost. cheers, -chris > > I highly doubt it.
