[asterisk-users] cpu usage for G.729 codec

G.729 is a compromise of bandwidth vs. CPU power. It takes more CPU but
less bandwidth.

It depends on what your want to do with the G.729.

Pass through does not involve any transcoding, that I know of, so it is
just an RTP packet movement, no different than the cost of other pass
through codecs.

I did work on converting G.729 to G.711 to disk storage in real time and
that took about 3% of a Xeon CPU for full duplex.

Memory wise each convert call might have used 640KB in buffers and
trash, but not much.

Do any one knows the formula to  calculate memory and cpu usuage for
channel on g729 codec,to know the hardware required for 100 concurrent
call.
