[Freeswitch-users] Tuning Up Freeswitch

[Antonio Teixeira]

Well this is a 2 X E5506
With 8 GB of Ram.

The Main Problem is that we use tons of DTMF + TTS + Dialplan Logic and as
you say Anthony this causes an impact on the total Supported Calls.

I'm building a new IVR server that we can deploy on another server so we can
ease the pain that mod_python is causing on the CPU.

TOP Shows AVG idle CPU at 93 %

Anyway for every performance increment i find i will post it here. Thanks
Anthony for your input i think i got your point , I'm assuming an SBC with
media bypass would handle a lot more calls  per profile but as you may have
guessed my objective is not SipTrunking but a high layer of service.

Anyway thanks alot.

Regards
Antonio Teixeira
