That is exciting.

I have the following information:

1) I did some performance comparisons years ago. The results not 
available on the web, but the test can still be downloaded here: 
http://svn.osgeo.org/osgeo/foss4g/benchmarking/geometry_libraries/
(it is already old, I did not check it - you might get some compiler 
errors in any library...)

2) Later a benchmark s done for a blog page. See the results here:
http://rogue-modron.blogspot.nl/2011/04/polygon-clipping-wrapper-benchmark.html

3) Performance is also measured (but not compared) in the robustness 
tests on the trunk, there are several tests there. Most of them test 
union/intersection/difference
