The git repo takes 6 wall clock seconds longer to clone and consumes
100M less space.

If you want your git repo to be smaller and can burn some cpu:
git gc --aggressive; du -sh .
485M .

Regarding remote svn diffs vs local git diffs:

time svn log https://svn.freepascal.org/svn/fpc/trunk
svn log https://svn.freepascal.org/svn/fpc/trunk  1.02s user 0.45s
system 5% cpu 25.414 total
time git log | cat
git log  0.49s user 0.09s system 37% cpu 1.531 total
cat  0.02s user 0.37s system 25% cpu 1.531 total

You can dump all the logs in 25 wall clock seconds for svn; 1.5
seconds for git. You can also do things like git grep, git log -S and
so on.

And you can work without a network entirely for days. You won't be
able to access things added since you last connected, but you can
commit, do diffs, merges and blames and search history - all without a
network.
