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?
