I think I've done it in both directions now, and it got faster, but still 
much slower than darcs1:

$ time darcs2 unpull --from-tag 2007-09-25 -a
Finished unpulling.
58.68s real   50.64s user   6.36s system   97% darcs2 unpull --from-tag 
2007-09-25 -a
$ time darcs2 pull -a ../ghc-darcs2
Pulling from "../ghc-darcs2"...
Finished pulling and applying.
53.28s real   44.62s user   7.10s system   97% darcs2 pull -a ../ghc-darcs2

This is still an order of magnitude slower than darcs1 for the same 
operation.  (these times are now on the local filesystem, BTW)

Cheers,
        Simon
