File system access is significantly slower on Windows because of 
case insensitivity, Unicode and more metadata accesses per file. 
This overhead is far from being negligible when accessing a lot 
of small files (on NTFS afaicr files < than cluster size are 
stored inside the special directory structure requiring special 
operation to extract and other such oddities).
