New subject: rtpengine transcoding benchmarks?

1 Mar 2018

Andreas-

...
  We've seen around 400 concurrent calls for
G711<->Opus on a rather
 slow 12-core E5-2420(a)1.90GHz for some first preliminary benchmarks. 
Was that using narrowband (8 kHz) for Opus ?  Otherwise sampling rate conversion is
needed.  Also I assume Opus DTX was disabled.

Also at what Opus bitrate ?

Thanks.

to be comparable to a lot of the
commercial options out there right now.
