The benchmark results submitted as part of the project documentation
for the XRender pipeline project showed not that impressive results
for swing benchmarks (the non-remote cases) and small operations (e.g.
20x20 image tests).
I did extensive profiling to find the causes and one major problem
seems to be very high per-primitive costs in Xorg-server-1.5 (caused
by an expensive implementation of dixLookupPrivate).
A fix is already in the works.
A more detailed analysis can be found in the updated benchmarks.html attached.
