I'm just creating this ticket so that we don't accidentally release Darcs 2.5 with a packs feature that makes --lazy slower. In the worst case, we can just hide the packs feature (or mark it as experimental).

Eric, could you please check again with the current HEAD? I have pushed a patchset from Alexey which should help with this a lot. Thanks!

Thanks! With pleasure. After optimize --http with the new code to get the smaller packs tarball: darcs get http://darcs.net --lazy --no-cache On my Mac on home cable modem darcs-2.4.98.2: real 105.99 user 1.15 sys 1.48 HEAD : real 17.37 user 0.94 sys 0.71 On my Linux machine at University: darcs-2.4.98.2 real 134.60 user 0.66 sys 0.40 HEAD real 11.78 user 0.95 sys 0.32 Congratulations, Alexey! PS: I think this is blog worthy... full timings may be good for that too. -- Eric Kow <http://www.nltg.brighton.ac.uk/home/Eric.Kow> For a faster response, please try +44 (0)1273 64 2905.
