[vtkusers] Why is vtkDelaunay2D so slow in VC++ 2005

Are you using the Debug build or the Release build of your program?

Debug builds will be significantly slower when there are many allocations
involved in an algorithm... If you are using Debug builds to judge
performance, don't -- you can only judge performance reliably in a Release
build when building software with the Microsoft compilers.
