The main reasons why the player uses more CPU than mplayer IMO are
1) updating gtk (like the time display and the slider)
2) slower plugins (like mad for mp3 decoding)
though I haven't benchmarked it and threading might be part of that
picture, too.

Gtk updating runs in an idle callback though, so that shouldn't be an
issue. As for the plugins you probably need to find out if you use bad
ones (which is a pain to do when you're not a gst hacker, I know).

I think we do quite well wrt speed though. Benchmarks are always welcome.
