What is the reported CPU usage, and how fast is your computer?

We haven't really optimized playback CPU usage very much.  If you (or
someone else) is interested in working on this - I would first look at
all the metadata signal emissions in e.g. monkey-media.  There's some
g_utf8_validates in there and such.  Also, these might cause spurious UI
updates, such as redrawing the song display thing (which is quite
expensive).

That's possible too.  Try just using the gst-launch pipeline in the
README to see how much GStreamer itself uses.

Is this during the "Refreshing songs..." stage?  If so...known bug. 
Actually, this bug had been annoying me too, so I just tracked it down
and squished it :)

* commited walters@rhythmbox.org--2003/rhythmbox--mainline--1.0--patch-59

Will be in 0.5.4.

It'll be fixed eventually...faster if someone else works on it :)

Cool :)
