I have fewer branches than tags, but I get something similar for "git
branch --contains":
[torvalds@i5 linux]$ time git branch --contains v2.6.12 | sha1sum
9d4224eec98ec7b0bcd5331dfa5badb9ef1fd510 -
real 0m4.205s
user 0m4.112s
sys 0m0.084s
[torvalds@i5 linux]$ time ~/git/git branch --contains v2.6.12 | sha1sum
9d4224eec98ec7b0bcd5331dfa5badb9ef1fd510 -
real 0m0.112s
user 0m0.100s
sys 0m0.008s
ie identical results, except one took 4.2s and with the patch it took 0.1s.
This is all hot-cache, of course, and on a fast machine.
