The following shows the output from several runs of a benchmark looking up 5.25 million randomly generated points in a coordinate space of 5000x5000 that contains 1/4 million polygons: 

c:\test>569929-b
1 trial of 5,25e6 points in 2.5e5 polys (33.094s total)


c:\test>569929-b
1 trial of 5.25e6 points in 2.5e5 polys (36.656s total)


c:\test>569929-b
1 trial of 5.25e6 points in 2.5e5 polys (33.250s total)


c:\test>569929-b
1 trial of 5.25e6 points in 2.5e5 polys (35.094s total)
