why my dummynet queue not work?

[jim song]

Brooks, Luigi,

Finally it is solved!

I found I have run to the false direction.  Because I am a newbie with 
dummynet, I am not confident with my setting at the begining.  :)

Actually, the low throughput is caused by 1323 option not enabled on 
the end host.

The setting is as below:
---------------------------------
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"Tcp1323Opts"=dword:00000003


Thanks for your helps!
