I was about to send the exact same response. Cache revisions every 100-200
patches and you are done. See "tla cacherev -H". You can even delete the
old ones you won't need anytime soon to save space, as it's a tar.gz of
the complete revision.
This can easyly be automated with a ~/.arch-params/hook script that adds
and deletes revisions transparently (contact me privately if you need it).
Just decide your needs, modify the script and gets will be very fast.
Commits are already fast since the inode optimizations.
It looks like this woud solve your initial speed requirements flawlessly.
Forget by now of the space trade-offs of the archive format, there are
open discussion to improve it.
I'll file a bug in savannah to ask for the tla get --hardlinks.

The problem is that it can become very big with kernel archives. Maybe
it's better to cache revisions.
