Is there any chance you could make the raw tcpdump files (rather than
the decoded text output) available? It's much harder to debug things
when information has been subtracted.
Based on what little is available here, I'm seeing what seems to be an
RTT that jumps around a lot, from a few milliseconds on up to 150
milliseconds, and causing TCP to misbehave. It's likely that this is a
kernel issue that needs to be investigated.
