Goals
Measure the impact of tweaks and features and dialplans on CPU utilzation.
Variables
- CPS benchmarks
- stack 250B vs defatult
- log levels
- SQLite on/off
- SQLite on ramdisk
- CSV CDR on/off
- XML CDR dir on/off
- XML CDR url on/off
- Call auth on/off
- Dialplan length 1/10/100/1000/10000 regexp entries
- DIALPLAN, LUA, outbound socket, ODBC, MEMCACHE bridge
- IVR vs SIP2SIP Bridge
- presence on/off
- RTP benchmarks
- NOMEDIA vs MEDIA
- call recording to RAID-1 on/off
- call recording to ramdisk on/off
- rtptimer soft/none
CPS benchmark results for 300 CPS and 0.05s call duration
