I looked over the tcpdump that was sent to me, and it appears that Jeffery
Hsu is right; by setting the sendspace down to 1024 bytes, you've caused
your system to send smaller than normal packets and have also caused the
system to send only one packet at a time, destroying performance.

In addition, there is a problem with dropped packets, but that's to be
expected on a wireless link, and it should be handled fine with a proper
sendspace setting.
