[asterisk-dev] How to get to 10.000 open calls

[Venefax]

Yes, I have the box. And I will get the calls next week. I was thinking to
use the Asterisk feature where you can start different Asterisk using -C
\path_to\config\file, and start 15 instances. But to be able to load balance
it is a nightmare, since many clients do not accept or follow redirects (SIP
302 Moved). I am out of tricks, unless I setup another technology for load
balancing but then why not use the same (x) technology for everything? What
technology would that be that can handle 10.000 sip connections, not
touching the media? My Cisco 7301 would not scale so far out.

Do you have the system now?

While it's most likely be a dream, identifying the current bottlenecks
might  be useful :-)

Just a few uneducated guesses of my own:

* More than one IP per NIC won't help and only cause some administrative
  issues
* I'm not sure how much the extra memory can help. I suspect htat if you
  boot the system with mem=<whatever_needed_for_16GB> the results won't
  differ greatly
* It would also be interesting to see how the results scale with various
  values numbers of cores. This is again something you can set at boot
  (numcpus=N). I wonder just how far from linear it will be.
