[OpenSIPS-Users] How to know how many workers configure / server support

[Brett Nemeroff]

It really depends on your application but I suspect that 200 is overkill.
What CPS are you running? What else is this server doing besides OpenSIPS?
Is your db on the same server? How fast are those queries returning? The
server is spinning doing something. How’s your disk IO look? I’ve seen very
high rate of logging so this. If you remove traffic, does load go back to
0?
