The Palm is requesting a window size of 1, which is strange
and might explain why performance is poor. The Palm is also requesting
a packet size pretty small (512). Can't help either.

It seem that the application is not really in a hurry as far
as sending data goes (the "rr" are just the stack waiting for some
data to send). And it send ridiculously small amount of data in each
packet. Very weird.
Note : you may want to try the latest patch available on my
web page to see if it make any difference...
