Anyhow, could you retry this test with the above change in methodology, and let me know if (a) the pull is still slow the first time and (b) if it's much faster the second time (after the reverse unpull/pull)?
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
