Dear diary, on Wed, Nov 09, 2005 at 11:20:22AM CET, I got a letter where Junio C Hamano <junkio@cox.net> said that...

Certainly not that. But I've fetched in the meantime and now show-branch takes much longer - median 0.078s (git-merge-base's median still stays around 0.128s). So possibly git-show-branch did some smart optimization right away in the previous case. I can try to track down the particular commits if there's any interest.
