Anyone know > what might cause this packet loss? Hmm. This is kind of interesting. 1. It's always 19-20% loss if you let it run for 400+ packets (almost always 19%) 2. This is on 4.4-STABLE from some time ago 3. The number of packets recieved is always a multiple of 100 when using the default packet size. 4. Machine speed doesn't seem to matter (it happes on an Athlon XP 1700+ and on a Pentium 166 Non-MMX). I can't help you track down the cause, but it is a neat effect. -- \ |_ _|__ __|_ \ __| Jason Andresen jandrese@mitre.org |\/ | | | / _| Network and Distributed Systems Engineer _| _|___| _| _|_\___| Office: 703-883-7755 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
