Hi Barend,

Thanks a lot for the details shared.
I will work in getting the fruitful results from these test suites.

Will reach out to you for any further clarifications, (if any).

Regards
Tanjot

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
http://svn.boost.org/svn/boost/trunk/libs/geometry/test/algorithms/overlay/robustness/
