Hello all,

        I'm making an application with twisted and i have some problem with 
it.

I need to be able to limit bandwidth for a group of connection. A group of
connection can be "incoming client" (client connect to the server) and/or
"outcoming client" (server connect to the client).

Another request is to limit the "global bandwidth" upload and download.

I've take a look at the htb module in twisted.protocols but i'm not convinced
about it.

About CPU usage, i've tryed the example shaper which use htb, and when i
download something twisted take all my cpu.

If someone can help me about my request and can explain me why shaper example
take lots of cpu ...

Thanks for your reply

Jol
