[Freeswitch-users] Performance testing

[Gonzalo Gasca Meza]

Hi Ken,

I'm using .wav, this is my ESL command:

originate
{sip_h_X-UUID=9d33a760-gmwz-qn1n-xvqz-qal4-9d33b25a89,sip_h_X-Campaign=3A252BEX9W,ignore_early_media=false,bridge_early_media=false,originate_timeout=70,bridge_answer_timeout=70,call_timeout=70,[leg_timeout=70],execute_on_answer_1='sched_hangup
18
ALLOTTED_TIMEOUT',origination_uuid=9d33a760-gmwz-qn1n-xvqz-qal4-9d33b25a89,origination_caller_id_number=+14081116805,RECORD_STEREO=true,execute_on_answer_2='record_session
/var/www/html/recordings/9d33a760-gmwz-qn1n-xvqz-qal4-9d33b25a89.wav'}sofia/gateway/kamailio/+14080001963
handle_calls

I created a separate volume for writing only recording files & logs.

I will consider increasing CPUs, do you think I still can remove some of
the modules I currently using to improve performance?

Thanks!
