</div>Some more factors this depends on:<br>
<br>
- type of the database (mysql, postgres..)<br>
- exact setup and machine configuration (DBs likes RAM)<br>
- usage of a local DB or a remote one<br>
- exact configuration of the UA and registrar, e.g. expires values, number of<br>
DB access per REGISTER<br>
<br>
In our experience registrar performance is not an issue. You'll probably need<br>
several machines anyway because of HA/ maintenance requirements. But because<br>
of this different factors its not easy to estimate for your special<br>
situation.<br>
<br>
You can find some registrar benchmarks at our website:<br>
<a href="http://www.kamailio.org/docs/openser-performance-tests/" target="_blank">http://www.kamailio.org/docs/openser-performance-tests/</a><br>
<br>
I'd suggest that you do some benchmarks with your setup, e.g. with sipp and a<br>
simple REGISTER scenario.<br>
