<DIV>fortunately we can do this in the same machine because it has an amount of traffic controllable by us so at any given time we can take it out or put more or use sipp, I will post the results as soon as I have something new, thank you guys a lot again</DIV>

<P style="MARGIN: 0px; TEXT-INDENT: 0px"><BR></P>Hello Juan,<BR>
<P style="MARGIN: 0px; TEXT-INDENT: 0px"><BR></P>as this looks more like a hardware issue to me i'd try to find issue that causes this particular server to be that slow. Somewhere it must spend this time. Some ideas:<BR>
<P style="MARGIN: 0px; TEXT-INDENT: 0px"><BR></P>- Start kamailio with only one worker children, and then use strace to see what its doing when its hangs<BR>- enable debugging (only for a few seconds if you've production load on the system) and then look to the timestamps where its spend the time<BR>- use the benchmark module as Daniel already suggested<BR>- try to replicate the setup in a lab environment and then use a load tester (e.g. sipp) to give some traffic to the system. then change certain parts of the configuration and setup to find the culprit<BR>
