that was an ugly one and I glad that Anca provide a fast and reliable 
fix for it.

once you enable the authentication, you actually start measuring the 
performance of the DB server and not of opensips - opensips it much, 
much faster than a DB server is able to response, so the db query for 
the password becomes the bottleneck.

what you can try to do is:
1) decouple authentication from DB - use a static password in the script 
to push it directly in the auth module (instead ofDB query)
2) to a benchmark (from the server where opensips runs) against the DB 
server, directly from mysql client - see how many queries per second you 
can do; this will give you a fair idea about who's guilty for the delays.
