Right, I didn't include the loopback or any other devices ifconfig
shows. (lo, ath0, wifi0).

Ya, it's only the laptop which is the fastest machine I have.  And
it's not busy at all.  It's just sitting at a gdm login with the lid closed.

Seems like hardware -- but other than errors in ifconfig (which is
shows none) I'm not sure if or where I can look for other indicators
that would measure the latency.  I guess that why those expensive
network analyzers exist.

And it's not consistent -- some times it's not too bad.

Just one of those frustrating mysteries. ;)

Thanks,
