(fwd) Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-current@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Hi... One of my staff connects to ki.net (-stable) using PPP, and pinging the other machines on my network, has been getting results that look like: --- ki.net ping statistics --- 50 packets transmitted, 50 packets received, 0% packet loss round-trip min/avg/max = 160.2/2307.7/4291.1 ms --- freebsd.ki.net ping statistics --- 50 packets transmitted, 48 packets received, 4% packet loss round-trip min/avg/max = 150.2/1017.4/3650.0 ms --- thrawn.ki.net ping statistics --- 50 packets transmitted, 50 packets received, 0% packet loss round-trip min/avg/max = 150.1/165.8/220.1 ms stoned:~ $ traceroute freebsd.ki.net traceroute to freebsd.ki.net (205.150.102.51), 30 hops max, 40 byte packets 1 ki.net (205.150.102.1) 183.382 ms 165.283 ms 159.4 ms 2 freebsd.ki.net (205.150.102.51) 149.22 ms 207.858 ms 158.942 ms --- freebsd.ki.net ping statistics --- 500 packets transmitted, 493 packets received, 1% packet loss round-trip min/avg/max = 150.1/176.3/610.2 ms Now, the only reason I'm sending this through is because freebsd is my only -current machine, the other two are -stable. If you look at ki.net's results, he's doing an avg of 2300ms over 50 packets, yet no packet loss. On freebsd, his average is half that, but 4% packet loss over the same number of packets. Both freebsd/ki.net are the same machine, except that ki.net has more hard drives. Both are using SMC8013 ethernet cards, both are DX4-100's and both have 16Meg of RAM. And, he's able to consistently get this packet loss by hitting the -current machine. Theories? I know there has been *alot* of software changes to the tcp code over the past few weeks...could they have affected something like this?
