[OpenSIPS-Users] recommended settings for performance

[Bogdan-Andrei Iancu]

Hi Søren,

The throughput of your opensips highly depends on your script - if your 
logic is complex, if it performs many external queries (db,radius, rest, 
etc). It is more test and see approach - monitor the load of your 
opensips and adjusted based on your observations .

Trying to answer to your questions:

1) assuming there is a need for CPU processing, you should configure a 
number of total processes (in opensips) at least equal to the number of 
cores - the opensips as overall app can use all the cores in the same time.

2) I guess you mean about memory ? if you have large CPS / parallel 
calls / registrations, consider increasing the shm memory  - anyhow, 
inspect the mem usage at runtime with "opensipsctl fifo get_statistics 
shmem: "  and re-adjust

3) if you script is I/O intensive (DNS, DB, RADIUS, REST), better have a 
large number of processes (32?). If not, try to correlated with the 
number of cores you have. Also, adjust on the run by checking the 
internal load via "opensipsctl fifo get_statistics load: "
