Hello,<br>
<br>
another metric is how many tcp/tls connections you have to handle.
Also, if you do caching or db only user location.<br>
<br>
For the proxies, a decent server these days (4-8 cores) with 2GB of
shared memory and 12MB of private memory for kamailio should be
enough. 16 to 32 children should be enough, more is no longer that
efficient, either you have some slow components (e.g., database,
dns), or too much traffic/users that you need another box.<br>
<br>
You may need to tune some of the parameters from usrloc (if you use
caching) for better performances.<br>
<br>
Cheers,<br>
Daniel<br>
