[gdal-dev] RasterIO slower on Windows

[Adam Kubach]

Hi,

It appears that my calls to RasterIO are about 10 times slower on
Windows than Linux when reading from the same dataset.  I wouldn't
think that there would be a noticeable difference.  Has anyone else
seen this?  Is it possible that the overviews aren't being used on
Windows?  Is there anyway I can verify that they are being used (Other
than a debugger)?

Thanks,
Adam
