[asterisk-dev] Regarding SIP performance

[Chirag Vaishnav]

Thanks. But I am looking for imrovement in code. Can we really do something 
to make it able to handle more number of calls? If we can do that we can get 
better performance on any machine. Like using sun spark you can fire 300 
call/sec then you should be able to do much more.

May be asterisk gives low performance because it is made to create channel 
between to different protocal and it handle RTP/RTCP also. If we think about 
sip to sip and peer to peer only can we do something to improve performance.

I know there are softweres like OPEN SER to do so. but I have lot of reason 
to use asterisk. So... help me. atleast give me some idea.
