a dlna solution based on rygel sounds more future proof to me.

You want to lower the the CPU usage in the mp3 deoder not in gstreamer
as you found out it is caused by the mp3 decoder. You'll need to get a
mp3 decoder that performs better. Some time ago people wrote a decoder
based on libmpg123, but it is incomplete and noone ever bothered to make
it mature and submit it for inclusion with gstreamer.
