I put the log files here:
http://www.cyrius.com/tmp/2.6.22
http://www.cyrius.com/tmp/2.6.23-rc8-sched-devel

I increased the time ipfer ran to 30 secs since your script runs for
over 15 secs. I got:

[ 3] 0.0-30.0 sec 331 MBytes 92.6 Mbits/sec 2.6.22
vs
[ 3] 0.0-30.0 sec 222 MBytes 62.1 Mbits/sec 2.6.23-rc8-sched-devel
