Goals
Test max CPS for FreeSwitch on SUN x2200 with all extras disabled.
max is reached when retransmissions start to occur (due to singlethreadness of sofia)
Tweaks
- ulimit -s 250 -n 200000 (-hp option adjusts the stack anyway)
- disabled CDRs
- dialplan
Procedure
- restart FS on test3 box
- run sar on test3 box
- run sipp on test1 box
- parse sar 1 second interval output and average out the upper half of the step period minus 4 last seconds (15s step = 4s avg, 180s step = 86s avg)
Variants
- call duration ZERO
- call duration 5s
- call duration 90s
Results
Max for zero duration (~700 sessions active)
