[SR-Users] Re: low performance with no apparent reason

The OP didn’t provide any additional info. Maybe he’s doing db operations. Maybe he’s running something else on the server. The traffic can be generally ok and then the OS is doing something weird or some other application is doing something weird that can affect kamailio for a short period of time. Then you have this extremely short bottlenecks and packets are dropped. And it all depends on the testing environment: CPU, synch or asynch logging, etc. One can stress kamailio on low performing hardware to reach the limit of a sistem faster and the results can be “misleading” for others that are used to test on server grade hardware. In the end, we agree with each other and my feeling is that we are repeating the same concept. Checking for dropped packets is always a good idea. How to deal with dropped packets depends a lot of the context. In most of my deployments I don’t need to mess with the udp queue size. For high cps traffic, from my experience, it’s a must. And of course, going overboard and increasing it too much just makes things worse. - ovidiu On Sat, Mar 23, 2024 at 20:02 Alex Balashov via sr-users < sr-users(a)lists.kamailio.org&gt; wrote:
