6e411d20440 (Initial draft of fast-import documentation., 2007-02-05) pointed out how much time a fast-import took on some hardware with a specific cost. Let’s further point out that this experiment was done in 2007. So modern hardware should have no issues with such a repo.

Also move the parenthetical to the end now that it contains four words.

That is a definite improvement.  Thanks.
