I'd do 2/4 or 4/4 assuming that "small" means "less than 4k".

The bigger block size might be a better long term solution (though you might
have a small performance drop in the short run). When we finish the data in
inodes feature, it'll allow you to store files within a single inode block
so the larger block size would be preferable for lots of small files. I
don't think we'll be able to retroactively 'stuff' inodes that already exist
though, at least not on a live file system.
