Hello guys,

I have FS box with 200-250 concurrent calls.  FS git 05/03/2012. 

Intel(R) Xeon(R) CPU           E5620  @ 2.40GHz

MemTotal:       12187540 kB

I use xml_mod_curl + php for dynamic directory\dialplan. Also I use lua scripts + mysql for some cases. 

I use sip options ping for some checking of productivity.

Sometimes (when loading is high) I have big delay with sip ping (>2 sec). The box which sends sip ping in same network with main box. 

My question:

1) Is it many concurrent calls for setup I have ?

2) If not, what the best way for understanding where I lose productivity ?

Please advise.

Thanks.
