Let me be the first to catch that arithmetic error
Let's say our delta size is 400MB (typical under load) and we leave

two thousand of those before deciding that we have enough

Sorry about that folks. I've lost all interest, it won't happen again.
Thanks for your valuable contribution. Now we are seeing

It's easy to be fast on empty filesystems. XFS does not aim to be
fast in such situations - it aims to have consistent performance
across the life of the filesystem.
In this case, ext4, btrfs and tux3 have optimal allocation

Btrfs appears to optimize tiny files by storing them in its big btree,
the equivalent of our itree, and Tux3 doesn't do that yet, so we are a
bit hobbled for a make load.
That's not a build load, it's a git load. btrfs beat all others
