Our system somewhat predates ublk; at the time we wrote it, FUSE was the most reasonable option. Moving over to ublk would require re-architecting around block devices rather than filesystems, but is indeed something we're looking at!

Fair enough, would love to see another writeup on the performance you observe even if it fails - in practice numbers are hard to come by.
