Thanks, that's what I needed to know.

Ahem... you don't expect me to embark on hacking Git without at least understanding that, do you?

Here we're speaking about the initial import. Committed on 17 April 2005 by Linus Torvalds, with the comment ``Let it rip''. 220 MB of changed files in a single commit. 2 minutes real time just to read all the files, never mind doing anything useful with them.

To put it mildly, Darcs is not optimised for that sort of usage.
