[Freeswitch-users] CPS per mod_sofia profile limited?

[Anthony Minessale]

There is a tradeoff between cps and audio quality and timing accuracy.

Try -vm -nocal if you want to mimic 1.0.4 we don't discuss performance here.

Yes, 1.04 offered a lot better performance in my test scenario, using
the same call scripts. I agree that the scenario isn't really realistic,
I should test with at least 30 second calls.

Thought about the same, and funnily enough that didn't help. But in the
long list of things I tried I don't remember if I tried it on 1.04,
without media proxying. I expect a much higher performance just
bypassing the media. I'll try again tomorrow on 1.04 and post the results.

I check disk performance using iostat and they're on 2% usage. It's a
10k rpm sas disk we're writing to, with ram cache on the raid
controller. Also -nosql didn't have any influence at all on performance.

Exactly. I'll adjust the lengt of the call to 30 or 60 seconds and then
try to see how many calls we can have. That's in the end what matters
really and not cps on it's own. Have to create a 60 second pcap first. :)

Nothing, it's a single entry dialplan and that entry is thus on the top.

Yep. :)

Thanks for the input so far!

Maybe after I get some final results I put it on the wiki for future
reference to load tests?
