[OpenSIPS-Users] Problem load-testing opensips with Auth

[Juan Backson]

Hi,

I fixed the "nonce" error with the latest 1.4.2 svn release.  Previously, I
got the latest release mixed up with old .so file.  Now it is working fine.
Thank you for the fix.

The only problem I have left is about the performance of opensips when Auth
is involved. Without Authentication, Opensips can process >10K registration
requests/s.  When Authentication is involved, it can only handle 80
registration requests/s.  The box in this case is a Pentinum dual core with
2G Ram.

After I moved the mysql DB to a qual-core Xeon 4G RAM box, cps of
registration requests increased to 550/s.  Is this roughly that I should be
expecting?

I hope to see the kind of benchmarking number that other people are seeing.

Thank you in advance for your help.

Regards,
JB
