But with SVN you don't fetch complete history.

You can do that with Git, too. And SVN is generally a lot slower to
clone the same repo. :)

FWIW:

[dannyb at dannyb-macbookpro3 11:54:38] ~/sources/llvm
(git-svn)-[newgvn-predicates]- :) $ gdu --exclude=debug-build -k
...
521724 .
[dannyb at dannyb-macbookpro3 11:55:00] ~/sources/llvm
(git-svn)-[newgvn-predicates]- :) $ gdu .git -k
...
305768 .git

an SVN checkout would have transferred the 521 meg:)

With zlib compression, etc, maybe they are about equal.

But SVN would not have transferred significantly less data here.
