[Freeswitch-users] Question aboutCPU usage.

Fri Jan 21 22:35:21 MSK 2011

Ricardo,

"I also installed the codec g729 for transcoding from g711 to g729  (for
testing purposes only)."
We're assuming you're using deepwalker's fs_itu_g729 codec?

If you're planning to transcode G729 it's always better to test with the one
you're actually going to be using. You can get completely different results
since they're different code bases.

fs_itu_g729 will use more CPU and memory than mod_com_g729 so you'll get
different load testing results.
It also has no concept of licenses, so there's no way of testing that you're
handling the conditions where mod_com_g729 has reached the license limit.
