this load tests are mostly about sip signal handling and not so much about rtp streaming but this moh class which i use had 100 files and random set to yes, so its atleast not soo bad. > [snip] > >> 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. This 330 concurrent calls was only the highest value which i had on a normal production system and its really hard to build a test setup which presents a system with 4000 sip peer doing some calls. but the sound quality was still good even with 10000 calls in my tests. > Regards, > Patrick > best regards stefan -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
