[geos-devel] speed difference between release and debug builds

[Fabian Hohmuth]

Hi all,

we're using GEOS via the C API under Windows (doing unions on a number 
of complex polygons) and noticed that there is a major (3x) speed 
difference between the Release and Debug builds. I somehow can't believe 
that the compiler optimization is that good. The defined preprocessor 
symbols are the same between the two configurations. Any hints where 
this could come from?

Thanks,
- Fabian
