I use database for lots of configs. On any given first request i do around 10 queries.

A while ago i measured the processing time (using bm_timer) when i was still using MySql and got times of around 6ms per first Invite and around 2ms for other in-dialog requests.

While i think those are big processing times, i don't think they should be the problem at a rate as low as 20CPS.

Thank you for your help :)

Ok, i reduced the number of processes and tried a few different values, but the performance hasn't changed a lot.

How can i debug this and find the bottleneck in my system?

Greetings Alex,

At the moment i'm trying to debug some issues with the server and try some solutions to see the impact.
With little load i'm getting some percentage of "503 Server Unavaliable" errors from Kamailio. I made some testing without using database for anything but Dispatcher and Accounting and the performance got way better.

Right now, on this server, under as little as 20CPS Kamailio is returning "503" on 1-2% of all calls. However, my CPU and Memory look like this:

%Cpu(s): 20.3 us, 6.1 sy, 0.0 ni, 73.3 id, 0.0 wa, 0.0 hi, 0.2 si, 0.2 st

Memory :

total used free shared buff/cache available
Mem: 1830 1172 382 109 274 375
Swap: 819 49 770

I have around 100 processes for Kamailio.

Cheers
