This is on target with my configuration I am working on. What kind of
dialplan were you using when running the tests.
Were you doing database lookups or just answering the calls and playing
hold music. Any example would be appreciated so we can quantify your test
results. I look forward to your response.
Thanks
Bryant
the dialplan is quite simple:
for the signaling up to 13500 CC i use this wait and for the 10000CC i
enable the musiconhold
exten => monitor,1,Noop(PERFORMANCE TESTS)
exten => monitor,n,Answer
;exten => monitor,n,MusicOnHold(806,45)
exten => monitor,n,Wait(45)
exten => monitor,n,Hangup
Iirc a long time ago there was a discussion about load testing by
playing MoH was not a realistic test. Something about all MoH music
getting streamed synchronized so basically Asterisk only has to stream
one file and sorta multiplex that single output to all the established
calls (legs).

btw my normal production machines which are just the same virtual
machines like this test system. i also had 330 concurrent calls, some
with transcoding, many database lookups, musiconhold, pickup ... and the
sysload was around 1.0 ;)
The difference (13500 with MoH versus 330 with a real dialplan) shows
that it makes sense to mimic your dialplan in your test scenario as much
as possible to see how far you can realistically push the box and still
keep things stable and sound quality good.

Patrick
