Can you cat /proc/cpuinfo and uname -a ?

Hi,

I've tried the tweaks (the ulimit changes and the disabling of sip presence) you suggested and it did improve a little, going from 8 CPS to 9.7 CPS.

My callflow is real simple. I'm calling an extension that plays a wav file and I hang up the call, 10 seconds after the start of the call, before the end of the playback.

You can see from the wireshark callflow below, that at a call rate of 15 CPS, after 20 seconds, it takes 17 seconds for a call to go from 100 Trying to 200 OK.

Do you have any other ideas of what could be holding down my freeswitch ?
