## why you shouldn't use git gc
http://metalinguist.wordpress.com/2007/12/06/the-woes-of-git-gc-aggressive-and-how-git-deltas-work/

### linus says
>So the equivalent of "git gc --aggressive" - but done *properly* - is to
do (overnight) something like

    git repack -a -d --depth=250 --window=250

>where that depth thing is just about how deep the delta chains can be
(make them longer for old history - it's worth the space overhead), and
the window thing is about how big an object window we want each delta
candidate to scan.

>And here, you might well want to add the "-f" flag (which is the "drop all
old deltas", since you now are actually trying to make sure that this one
actually finds good candidates.
