Hi all, I'm testing Freeswitch using ESL interface, recording and SIP UDP Calls at a rate of around 5 CPS. Freeswitch receives ESL requests and proceeds to send call to PSTN Emulator, once call is answered I start recording. I have noticed around 40% CPU utilization when recording is not enabled and ~60%+ CPU when recording is. I created/mount a volume specifically to store the recording files. (ext4) *Server specifications:* EC2 server (t2.medium) 2 vCPUs, 2.5 GHz, Intel Xeon Family, 4 GiB memory. FreeSWITCH (Version 1.6.9 -16-d574870 64bit) I followed instructions at: https://wiki.freeswitch.org/wiki/Performance_testing_and_configurations *[Questions]* a) How to strip down Freeswitch and remove non-used modules? Features I need: *esl, recording, loopback, bridge, sip, spandsp, cdr_csv.* My modules: *fs_cli -x "show modules"* http://pastebin.com/BQSxzFDE b) I would like to see which module is using X/Y amount of CPU cycles/memory in Freeswitch is it possible?. *fs_cli -x 'show status'* UP 0 years, 0 days, 1 hour, 2 minutes, 15 seconds, 541 milliseconds, 286 microseconds FreeSWITCH (Version 1.6.9 -16-d574870 64bit) is ready 18192 session(s) since startup 90 session(s) - peak 93, last 5min 92 5 session(s) per Sec out of max 30, peak 7, last 5min 6 1000 session(s) max min idle cpu 0.00/75.57 Current Stack Size/Max 240K/8192K A sample image is below: 40% steady (no recording) a peak when I enabled recording.
