Calculating and doing work like this on the server would not scale well.

If you haven't, you should review some of the old threads on speeding
up blame. Dan Berlin made a lot of improvements in the SVN 1.2
timeframe and learned a lot about what does NOT speed it up.

You should really search around for all of the threads he commented on
to get the complete picture. I think he also provided ideas on what
more could potentially be done in the future. Such as this one that I
do not recall was ever done.

Maybe the thread will explain why.
