A decade ago I was dealing with map tiles for the entire globe, stored each in it's own file, and reiserfs was dramatically better at dealing with all the small files associated with this: there are a lot of solid blue and solid green tiles in the globe. Reiser's idea of what a small file is was 1-2 orders of magnitude smaller than what ext3's idea of a small file was. More recently our map tiles are limited to a single US state, and we are using XFS, but because of the much smaller data set size I haven't really done any optimization beyond hard linking duplicate files. I inherited that choice, so I don't know what went into that.
