Hi!

I tried to test openser's call setup performance. Scenario: INVITE - 180 - 200

Server: 2 x P3 1266MHz

listen=UDP:... children=100

I used SIPP for testing.

I used sipp and the simplest openser config (just forward() ) and couldn't get very good. It seems that the limitation comes from sipp. You can try to use multiple sipp servers shooting at same openser to see if you see some differences. CPU used by openser was insignificant when the peak of cps was achieved.

1. Although the config is rather simple (no DNS, no DB, no lookup) I

can't get more than 700 INVITE transactions per second. Shouldn't this be higher (AFAIK ser powers the whole bay area on a handheld PC)?

bay area is about 300 call setups per second, and indeed, this performance was achieved on a iPAQ, with 0.8.x about three years ago, using the basic config file with no database backend.

2. With children = 100, I can see more than 200 threads and lots of

unix sockets opened, although no DB is used. Why?

the number of children is related to the number of interfaces openser listens to and the type of transport protocol enabled (UDP, TCP).

what is the name of the opened unixsock?

3. openser core dumps when children=200

Any backtrace?

Cheers, Daniel
