<br>
I'm currently benchmarking an ESL program that use both outbound and inbound mode and notice a quite large memory usage for the FreeSWITCH process compared to a dialplan that has similar actions (8 set (half multiset), 1 sched_hangup, 1 bridge).<br>
The FreeSWITCH process use about 2 Mo per call and about 180 Ko without ESL.<br>
<br>
This does not look like a leak, the memory usage is stable and proportional to the current calls, Valgrind does not show anything special either.<br>
<br>
What was tested:<br>
- Pure dialplan while running only the inbound ESL subscribing to some events (CHANNEL_HANGUP, CHANNEL_HANGUP_COMPLETE, CHANNEL_EXECUTE_COMPLETE, SESSION_HEARTBEAT) for all channels, inbound ESL does not increase memory consumption,<br>
- Outbound ESL that just close the connection at the beginning of the dialplan, same memory usage as a complete ESL program,<br>
- Outbound ESL linger set/not set, no change,<br>
- Outbound ESL parameters async/full present or not, no change,<br>
- Versions 1.10.5~release~17 and 1.10.6~release~18, no change.<br>
<br>
Does this kind of resource penalty is to be expected?<br>
What could cause these differences?<br>
For those using outbound ESL, how much memory does your FreeSWITCH use per call?<br>
