[Freeswitch-users] Hardware for Freeswitch setup

Thu Jun 5 01:17:48 MSD 2014

I think you will be fine with the XEON setup.  Remember to configure enough
file handles (ULIMIT) and to follow the instructions in
https://wiki.freeswitch.org/wiki/Performance_Tuning, specially about the
tmpfs.  If you go with SSDs, there are some good suggestions there too.

You also have to be careful with logging on a loaded production system.
 DEBUG mode or SIP Trace in a FS with that many concurrent calls can
quickly grow.  Remember that you will be writing 150 files concurrently.
 Many caches/buffers help when reading files, but writing is another
matter.  Is 150 concurrent calls you average or your peak expected calls?
 What is the peak?  How much room for growth do you want to leave?

Make sure that whatever you use to transcode offline can handle G711.
