[Freeswitch-users] Performance Testing

Sun Jul 8 01:06:55 MSD 2012

I just know the actual data size of mod_json_cdr is smaller than
mod_xml_cdr... are you sure it's the CDR generation time and not the cpu
usage of writing it to disk?
Try a) mod_cdr_csv instead, b) mod_json_cdr instead, c) turning off all
logging and/or d) writing the CDRs to a ramdisk to see the new usage.

AND.. as said before.. calls aren't usually 4 seconds. "good" traffic is on
average 180+ seconds.
