Hi, Some days ago I published the first version of (candidate) Boost.PolyCollection at https://github.com/joaquintides/poly_collection Performance tests are available at http://rawgit.com/joaquintides/poly_collection/website/doc/html/poly_collect... but GCC and Clang were run in a Travis VM and the resulting figures are noisy and not sufficiently accurate. I'm looking for volunteers willing to run the performance suite in one or more of the following environments: * Recent GCC, 32 bit * Recent GCC, 64 bit * Recent Clang 32 bit * Recent Clang, 64 bit The full suite in one environment takes 1.5-2h to execute. If you're interested, please contact me privately (so that we don't pollute the mailing list) and I'll provide you with further instructions on how to do the testing. Thank you! Joaquín M López Muñoz
