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

[Mikhail Demekhov]

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?
