XP does a lot more than just displaying the files.
For instance, it creates an alternate stream for each image file, 
containing a thumbnail of the image. FAT-32 files don't have streams, so 
there is less processing involved.
FAT-32 is a leaner file system, but it's less robust, and slower for 
directories with lots of files. NTFS suffer less performance degradation 
when files are getting fragmented.

Besides, don't use windows explorer to time directory access.
To display my 20000 files, it takes nearly 5 seconds. Probably the files 
are read and sorted before being displayed. Take also into account that for 
each file an icon must be displayed.
