Fwd: How will cairo influence GTK's performance?

First of all thanks for listening and not beeing angry ;-)

As far as I know pango only sends the pixels if no render-extension is
available - if render is available it caches images of the glyph using
render.
However I am not an gtk professional so I may be wrong here (would be
a great starting point to work on if no caching takes place?)

The fact that pango could be responsible for the slowness I experience
with mozilla and especially eclipse are proofen by the fact that
low-level swt benchmarks show a compareable performance of primitive
draing functions, only text is about 3-5x slower than on the win32
platform. But what are the parts of pango which eat up all the time,
do you think it could lie in an unoptimized interaction with the
x-server or in the layouting code?

Thanks in advance, lg Clemens
