[Insight-users] File read time, 2d vs 3d

Wed Apr 6 18:16:14 EDT 2005

I did a small test reading 200MB of slice images in raw meta-data format (495 slices) vs. the same data in a single binary VTK file. The slice reading was about 60% faster on average (I was sure to stagger the reads to avoid OS caching). This is on a Win XP 1GB RAM computer. This seems very counter intuitive. Is this due to the VTK file format, which format is fastest for constant IO?
