You must have something setup strangely cos it would definitely reduce your overall cps to use ESL but not down to 2 CPS. Did you look over the server stats like top etc and look for any misconfiguration? On Thu, Aug 11, 2011 at 6:56 PM, Tihomir Culjaga <tculjaga@gmail.com> wrote:
is there any other method than esl to controll calls on FS from an eternal application? will mod_curl or mod_xml_curl get better performance?

Hi Anthony, thanks for your response ...
this is what i have:
esl_filter(&handle, "unique-id", esl_event_get_header(handle.info_event, "caller-unique-id")); esl_events(&handle, ESL_EVENT_TYPE_PLAIN, "CHANNEL_DATA CHANNEL_EXECUTE_COMPLETE CHANNEL_HANGUP");
what do you suggest i put there ?
is the inbound method less costly ?
I modified testserver.c just a bit...

try removing the filter and event subscriptions it's costly to consume all of the events especially at 75cps.

hello,
im wondering how much performance do we loose when using ESL instead of running it via dialplan?
without ESL with a fine tuned FS and a short dialplan ( answer, playback like 20 seconds file, hangup ) im able to service 75 CPS. On the same FS, when i use ESL to answer the call, playback the same file and hangup, im not able to run more than 2 CPS... this is a huge impact and i really can't believe it.
I'm using event-socket outbound e.g.:
<action application="socket" data="127.0.0.1:8088 async full"/>
my extension looks like:
<extension name="ESL_C"> <condition field="destination_number" expression="^(6666)$"> <action application="socket" data="127.0.0.1:8088 async full"/> <action application="sleep" data="1000"/> <action application="hangup"/> </condition> </extension>
im using testserver from lib/esl/ and i just removed the conference command and added the playback one.... also i moved the esl_debug lvl to 0
anyhow, FS cannot run more than 2 CPS compared to 75 CPS when the playback is done from the dialplan.
Please, can someone give me a clue on what is going on? Maybe im doing something wrong? how to get maximum FS performance using ESL ?
Regards, Tihomir.
