I agree. Woody Dickson said
What I found so strange was that while CPU usage remains pretty low
and distributed among all cores at 190 - 200 calls per second.
Then, after added a few more calls per second, all CPU becomes fully
utilized.
I did not interpret his comments as having anything to do with
criticizing or questioning the performance of freeswitch. His question
was one of curiosity about the extreme non-linearity of the processor
load suddenly surging by adding just a few calls. If I had seen this
same behaviour I likely would have asked the same question.
Just my two cents worth.
