Okay, yeah, inodeprints won't help with that.  But it's still a bit
odd; 'attr get' and 'attr set' are both ~0.1s for me here, on
monotone's tree, which is ~1700 files and ~13 MB (though only the
former should matter for attr get/set, since it doesn't have to touch
any file content).  That's still maybe longer than you'd like, of
course.

It'd be interesting to see a profile of where monotone is spending its
time on those command, if you happen to have appropriate tools
available...

The real solution is to figure out what extensions would be needed to
move all of this inside monotone, of course.
