 From discussion of the regressions on IRC, I'm given to understand  
that hashing makes many things faster but a few operations on very  
large repos are now slower.  As darcs1 was uniformly almost unusably  
slow on such repos, the result is that they're somewhat faster in  
general but some operations are still very slow; work is still being  
done to optimize these.

That said, I think a large part of the point behind darcs2 is to fix  
some of the odd corner cases in patch reconciliation that could lead  
to having to throw out your repo and start over in darcs1 (which I  
had to do several times with my ghc repo).
