We appear to have some big TCP problems in -stable (and presumably in -current as well). Anyone wishing to look at traces is welcome to retrieve http://khavrinen.lcs.mit.edu/test{,2,3,4}.tcpd and take a look. Warning: these files are very, very large: 95M test.tcpd 108M test2.tcpd 107M test3.tcpd 15M test4.tcpd Each trace shows a single large file transfer from a 4.4-stable machine to my -current desktop over a local-area network. test4 was aborted about 10% into the transfer so that you have a chance at looking at the whole thing in xplot. There are multiple pathologies visible in the results, but a good place to start would be around :56.44 in test4. -GAWollman To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
