OK attached are 4 raw tcpdumps of 1000 packets each. One from the
start and one from steady state.
The slow set was done like this:
on ia64: netcat -l -p8888 > /dev/null
on work: netcat ia64 8888 < /dev/zero
the traces were done of work with slow1 started right before the
netcat on work was exectued. And slow2 started after it acheved
steady state at 18MB/s.
The fast set was done like this:
on work: netcat -l -p8888 > /dev/null
on ia64: netcat ia64 8888 < /dev/zero
the traces were done of work with fast1 started right before the
netcat on ia64 was exectued. And fast2 started after it acheved
steady state at 42MB/s.
