I wondered why my .git directory of drakx-net was using about 70MB of disk space (I am accessing the SVN repository using git svn). Of course, I have read that periodic git repository clean could drastically save space and speed, but – what the heck – it is just a bunch of text files. So I never bothered with it.

However, after running git gc on top of drakx-net directory, the .git directory size went from 70MB down to 4MB. A 17.5x improvement! Unbelievable!

So I did the same to msec repository, with quite similar results — from 21MB down to 3MB!

So a mental note to myself – run git gc always. It rocks.
