Given [1] I have no doubt that you should see a difference between
mke2fs from e2fsprogs 1.41.0 (which will allocate the journal at the
beginning of the filesystem) and the latest tip of e2fsprogs.
It would be interesting to see how measurable the difference is,
though. I'd recommend doing "mke2fs -t ext4dev" using both versions
of mke2fs, and seeing how much the difference it makes.

I was thinking of trying this on a much larger disk (1TB) - the article
reports on a 4GB partition which is pretty tiny,
