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

[Ken Rice]

Keep in mind that top showing 125% is VERY misleading... lets say you have a
10 core system for the sake of example, 125% in top means you are using
roughly 12.5% of the total CPU Power of your system.  This is because TOP
takes the individual core percentages and adds them up...

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

Hello!

I have installed freeswitch using apt-get on my debian 8 sersver from
https://freeswitch.org/confluence/display/FREESWITCH/Debian+8+Jessie
block under title 'latest release branch:'

My server hardware:
2xCPU AMD Opteron(tm) Processor 6262 HE
64 GB RAM

I'm using calls with bridging from voipgw1(2,3) to gw4(5,6), G711A on both
leg A and leg B core.db in TMPFS

Through my server takes about 125 simultaneous calls

CPU load about 125%! It is very high in my opinion.

How to fix it?
