I am getting 11.6 Mbyte/sec raw network speed in and out (using a pair
of simple netcat-like programs that just spew data to the network or
read and discard it) with both linux 2.6.22 and 2.6.23
Outgoing this uses 85%system cpu and leaves 14% idle time.
Incoming this uses 97% system cpu and leaves 2% idle. (94% and 5% with 2.6.23)
Might it be that your http-serving (or -consuming) application is
limited by the available CPU power on the box? You could try watching
"vmstat 5" (or "top") on it while a transfer is in progress
