Would anyone with knowledge of compiler and runtime internals be able to make an educated guess as to how such a speed gain of factor 10 is possible? Is anyone else seeing similar speedups in boost or in the geometry library when compiling with Visual C++ 2010 RC (HINT: it's a free download, so anyone can try it out until end of June 2010).
VC++ 2010 now has the iterator checking disabled by default; It is probably unlikely that you were unknowingly running with checking enabled, but that would easily explain the speedup. HTH, -- gpd
