 |
|
Hello,
i'm trying to use freeswitch as a redirecting server meaning FS has to receive an INVITE and according to some rules it will redirect calls to other destinations.
CALLING_USER FREESWITCH SOMEWHERE
INVITE ------------------------------->
<------------------------------ 100 Trying
<------------------------------ 302 Moved Temporary
ACK ------------------------------->
INVITE--------------------------------------------------------------------------------->
Well, wverything works well except i have perfromance issues .... on my HW FS cannot do more than 40 CPS (INVITE answered by 302 Moved Temporary). When i increase the rate, FS starts delaying 302 response. Right at 50 CPS i see "calls" being build up in FS and the delay begining to grow.
When i observe the machine, load average is almost nothing (load average: 1.41, 0.61, 0.60) CPU never goes to 100%, and i see only one thread taking most load... all others are just sitting there with 1-5 % CPU time.
This looks to me as FS handles 302 messages in a single thread?!?!

Of course, i've tuned the machine up
ulimit -c unlimited
ulimit -d unlimited
ulimit -f unlimited
ulimit -i unlimited
ulimit -n 999999
ulimit -q unlimited
ulimit -u unlimited
ulimit -v unlimited
ulimit -x unlimited
ulimit -s 240
ulimit -l unlimited
ulimit -a
Started FS with minimum modules but still 40 CPS seems to be the limit.
So, is there any way to improve performance?
Tihomir.
