[asterisk-dev] Asterisk Performance as a B2BUA

[Di-Shi Sun]

Hi Pavel,

Thank you for reviewing the test results and comments.

Frankly, I do not think comparing OpenSER/SER with Asterisk can bring us
much useful info. We tested OpenSER/SER as a transaction stateful SIP proxy,
and tested Asterisk as a B2BUA. Asterisk did much more work.

Just some simple data if you interested in, OpenSER/SER can handle 200 cps
on one core of Intel Xeon 5140 dual core 2.33 GHz CPU. Asterisk can handle
8.5 cps on two Intel Xeon 5140 dual core 2.33 GHz CPUs, one way audio,
without codec transation.

Regards,

Di-Shi Sun.
