Negative. ;-) I didn't try gitk myself, but according to Nick Riviera it eats 1.6G... Otherwise, assuming that you have at least git-1.2.5, git-whatchanged on the whole tree should be roughly equally fast as it was before grafting, but git-whatchanged on individual paths is _significantly_ slower. That said, 1.3.0rc2 should already have Linus' optimization which should fix or at least mitigate the performance hit on narrowed-down git-whatchanged. -- Petr "Pasky" Baudis Stuff: http://pasky.or.cz/ Right now I am having amnesia and deja-vu at the same time. I think I have forgotten this before.
