That result is suprising! but i have DELL 2950 with 2 X 3.0GHz CPU on 
6GB ram, equiped with 8e1 link (2 sangoma A104D)  running FC5. I 
installed chan_ss7-1.0 with asterisk-1.2.25 doing transcoding, and each 
time calls get to 120+ the cpu is fully utilized.

the calls come from sip to the ss7 link.

can someone advice me on what I can do to improve the performance.

NB. I felt we re talking on the same topic thats why i added my own 
experience.
