this issue was mostly solved by cairo 1.4, so using gtk+ 2.10 or 2.12
with a fairly recent stable cairo release, should approximately yield
the same performance as a pre-cairo gtk+ release - even on embedded
platforms.

I'm only referring to gtk+'s own performances and its usage of cairo;
heavily using cairo on an embedded platform is still bound to cause
performance issues.
