This info is from the 1.99.3 or 1.3.99 kernels.  (can't tell the 
difference in this respect.)

I have no idea. Is there an error message or way to tell?

If that means 1-3 second periodical pauses, yes.

Never seen it in any kernel.

Never seen it.

Searching through the tcpdump I sent you, I don't find a large number of

I wouldn't say there's a large overall throughput performance problem,
just long pauses every so often (unpredictable, but on average, I'd say
every 10-15 seconds.)

Don't have one.
