[Freeswitch-users] Hardware for Freeswitch setup

[Oscar Franzen]

Thanks!

I forgot to mention that we want to use WebRTC in the near future as well.
Is there anything special I have to consider for that?

So you basically think the IO for recordings is going to be the main
bottleneck?
I am not entirely sure I can do transcoding at the storage server but I'll
look into it.

As I understand it FSW has to do some sort of transcoding when mixing two
channels to record them? Is it possible / would you recommend   to record
to g711 (I think this is the used codec)? And then later transcode it to
mp3 for long time storage?

What other bottlenecks am I looking at? What are some usual performance
problems and when do you usually encounter them?
My initial idea was to go with a modern multi core Intel Xeon processor and
multiple network interfaces. Is the next thing to focus on storage
performance?
