I belive your first step would be getting a more detailed profile
using proper profiling tools (gprof, oprofile). Also, compare outputs
as it could be cairo is being faster only because is not doing everything
needed to render a specific animation.

Note that gnash AGG renderer is known to be slow at rendering bitmap fills
and that a bug (fixed in trunk) made this worst by smoothing bitmaps even
when not supposed to.

If you find two movies being rendered at comparable quality by cairo and
agg, with the latter taking more time, publishing the profiles would
help. See http://wiki.gnashdev.org/Profiling and add a new page from
there for the testcase.

Thanks.
