[Freeswitch-users] Settings for maximum performance

[Max Clark]

Hi all,

We are evaluating FreeSWITCH as a replacement for our current
commercial SBCs - before anyone points it out, we need a B2BUA for
sane CDR generation (aka billing) and there is some ideas for future
functionality that would leverage more of the FreeSWITCH platform.

That being said we are currently forcing static IPs, disabling
registration and presence and setting inbound-late-negotiation for the
sip profiles. "Client" gateways are being authenticated using remote
IP ACLs and a dial string prefix. The dialplan looks like this...

The box in question has two Intel Xeon 5130 dual core processors w/ 4
GB Ram (being upgraded, trying to figure out how much ram we should
have). Disks are 4x 15k RPM SCSI in a Raid 10. Operating system is
CentOS 5.4 x86_64.

FreeSWITCH is being started with "-nc -nonat -waste".

What things should we be looking at to squeeze as much performance as
possible out of these boxes?

Thanks,
Max
