openSUSE started with 64KiB as well, but that was found to have massive memory overhead with smaller files, so it was switched back to 4KiB.

Yeah, see e.g. the Linus Torvalds rants about the "optimal" base page size.

You can probably make a good case for the optimal base page size being larger than 4kB today, but probably not by very much. Maybe 16 kB or so. But then it's not a huge advantage over 4 kB which has the benefit of compatibility, so, meh..
