I know this library but didn't test these aspects. All our projections 
are converted from proj4 to C++, and by this conversion alone they are 
slightly faster. It is indeed interesting to see if there are 
differences with this library.
About accuracy: we will support both double and high-precision 
arithmetic types and it is also interesting if there are differences here.

We don't have yet official performance tests for projections in the 
suite Mateusz pointed to. Actually the projections are an "extension" 
and were not part of the review, even if Boost.Geometry is in the next 
release or in 1.44, it might be that the projections are still not there 
yet, we have to harmonize some things as earth models.
