hmm... large rtt, which suggests that someone is not servicing the queues
fast enough.

this is for the 1gbe machine in the room with me

11/status:Established qin 0 qout 0 rq 0.0 srtt 0 mdev 0 sst 2920 cwin 61390 swin 1048560>>4 rwin 1048560>>4 qscale 4 timer.start 10 timer.count 10 rerecv 0 katimer.start 2400 katimer.count 2101

i would suggest turning on netlog for tcp while booting and caputing the output.

sorry for the short investigation.  gotta run.
