Hi !
<br>
<br>
I am chirag from india and I am working with SIP part of asterisk.
Currently I am doing testing with SIPP tool. Now the thing is that
asterisk is not able to handle more then 550 concurrent calls with call
rate 100 call/sec (on my amd 64bit dual core machine with 2 gb ram)
which is to less. I am doing this with canreinvite mode so there is no
issue of RTP traffic. I just want to astablish peer to peer call thru
asterisk. As i have said doing 550 call with 100 call/sec ( I hang up
calls after some time so this is including all invite and hangup
related massages) it consume full processing power and retransmission
starts if i increase number of calls.
<br>
<br>
If i keep firing 100 calls/sec without hangup retrans starts after
3200 calls.
<br>
<br>
Can any one tell me why it is so? is there any way to increase number
of concurrent calls with same or more fire rate?
<br>

Yes - run Asterisk under Solaris on a Sun Sparc system. If you want
serious performance (>300 calls/sec) and reliability, Sun's Sparc
systems are the way to go. Something like a dual 1GHz SunFire 280r or
perhaps an older 10 processor E4500 that can be expanded to 14
processors and has the ability to hot swap processors and memory <i><u><b>without</b></u></i>
being re-booted! Running asterisk on Solaris/Sun Sparc systems will
outperform any Intel platform by several multiples. Before anyone
brings up price difference - the 280r is 2 generations old and the
E4500 is 3 generations old and both machines can be easily found for
<$3000 and will outperform the latest Intel/AMD platforms costing
considerably more.<br>
<br>
Unfortunately, it seems that the predominate concentration of effort on
Asterisk is for an Intel platform which, in my opinion and 15+ years of
experience providing commercial services simply do not standup to the
performance and reliability of Sun Sparc systems. And, from a business
standpoint Sun Sparc systems provide more than 3 times the ROI of any
Intel platform.<br>
<br>
And no - I don't work for Sun nor do I have any interest in selling
hardware. I am just passing on our own experience. We are running a
commercial production hosted PBX system using Asterisk on Sun Sparc
systems very successfully.<br>
