It would be interesting to see a comparison on the same filesystem. E.g. 
fat32 or ext2 (using ext2ifs). NTFS is a bad example because it is 
implemented on Linux using a user file system driver (fuse), which might 
influence the performance test.

@Martin: How does the IDE ask for the last modification time (on Linux 
and on Windows)? I can then crawl through the source code (for Windows 
using ReactOS) to see what both OSes are basically doing.
