Juan,
I had similar problems with CentOS 5 x86_64 on a server with multiple dual-core Opteron processors (a Dell Poweredge server). I was unable to find the root problem, but I found that using the 32 bit version of CentOS 5 on an Intel platform resolves the problem. I also tested with various Debian distros on the Opteron-based server and they performed properly. There is something about the combination of CentOS 5 64 bit, Dell servers, Opteron processors, and Kamailio that doesn't get along.
While I suspected DNS-related issues (as did some of the replies on this list), that wasn't it.

hello
I installed kamailio in a pc with dual quad core @ 3.3GHz, 4 GB RAM and see that kamailio is very slow answering to INVITEs from the inbound carriers. The DEBUG is set to 3 and the idle CPU lowers only to 87% or 90 %, which is still decent but anyways the performance is very bad.
This is the first time that I see this, I have it installed in other machines with less resources, same OS [CentOS 5.2 64 bits] and it is performing very very good. I know that a high debug level is a enemy but in my case is set to 3 like in the other system, and it is using the same configuration file. What other thing may affect the performance?
I have made sure that it is not a network issue because the captures are taken in the same machine and I see multiples INVITEs hitting it and no response at all until more than 2 seconds
I would appreciate any help or suggestions
cheers
