What are you testing against? What OS, Hardware, Distro and such?
NOTE No 2 : I tried using asterisk (as a point of reference - don't
get
me wrong - I am not trying to start a flame war here). And it
succeeded
doing on the same hardware 60 calls/sec with a channel limit of 400
sim. calls using only 50% of the cpu (maximum). No under any
circumstances I have seen the behavior above (this inability to hang
call legs in a timely manner). Even when I pushed asterisk to the
limits
(80 calls per second 600 max call limit) and it started failing on
some
calls it never failed to hangup the calls for both legs on exactly
10 secs.
Load testing is a science and you can do it wrong most of the time
unless you know exactly what you're doing. If you're going against
the default dialplan its heavy and not something I would load test
against.
NOTE No 3 : As you can tell I was using a very small machine for my
tests. When I moved the same tests to larger installations (Quad Core
Opterons and Xeons) I got proportional results to the above.
What are you testing on now? Hope its 64bit.
