[Freeswitch-users] Debian8 FS-1.6.10 simple bridging and high CPU load

[Ken Rice]

Different configs with FS can lead to orders of magnitude differences in load on the CPU... things like how much media, how much transcoding, how much media interaction.... all affect load... even something such as transcoding from G711 to ilbc vs g711 to g722 can lead to massive differences in CPU usage.... what you are seeing may be just what it takes....

My colleague from another city said that his system СentOS-6.5 and
FS-1.4 on the CPU load is very small.
"top" shows loading a few percent at 150 the same as my server calls.
A colleague was very surprised when I saw the CPU load on my server.
Here I am trying to figure out what was wrong.

Mikhail Demekhov
