Actually this script did [1] http://progetti.arstecnica.it/tailor/attachment/ticket/178/testtahoe.sh using current tailor.

Uhm, are you sure that's the effective command executed *whenever* you hit the browser? With darcs v2, trac-darcs should really use $ time darcs query contents --match \ "hash 20081124204046-e01fd-b4d82d92f5fc8d9af65af44ccce8c29279fb73af.gz" \ src/allmydata/interfaces.py | wc -l 2169 real 0m2.150s user 0m1.576s sys 0m0.556s Of course, these days most of the time "the user" is actually some spider, and its a matter of time that one of requests get fullfilled and cached after that. Just a workaround, to say the best. ciao, lele. -- nickname: Lele Gaifax | Quando vivrò di quello che ho pensato ieri real: Emanuele Gaifas | comincerò ad aver paura di chi mi copia. l...@nautilus.homeip.net | -- Fortunato Depero, 1929. _______________________________________________ darcs-users mailing list darcs-users@darcs.net http://lists.osuosl.org/mailman/listinfo/darcs-users
