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.

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)?

2. With children = 100, I can see more than 200 threads and lots of unix 
sockets opened, although no DB is used. Why?

3. openser core dumps when children=200

regards
klaus
