I found some old not-yet-rebased branch (with 3 commits) and tried rebasing it.
I saw no time difference - maybe I'm doing it wrong?

I did following for both true and false config setting:

git checkout -b test_rebase old_branch
time git svn rebase
git checkout master
git branch -D test_rebase
<repeat>

Results I got:
13.7s 13.4s 13.6s (config: false)
13.6s 13.6s 16.6s (config: true)

The last "true" result is higher because rebase had to fetch one new revision.
