Well, actually the problem was the virtualization ... Virtio modules weren't loaded in my kernel, so i had slow performances for that reason. However thank you very much :) but i have posted also another question, about the dispatcher performances ... Basically i have a dispatcher in front of 2 proxies and i checked that it is actually able to manage just 2 Kamailio proxy istances (all the 3 components reaches 100% of CPU load with an equally distributed traffic). For which concern the DNS i checked that, by using Kamailio DNS cache mechanism, it is done just a single DNS query at the beginning of the call. Any suggestion? Or is it normal for the dispatcher to have this performance?
