Performance benchmarks-1.5 results show significant regression in 1.6

A user supplied me with results of running the benchmarks with 1.5,
1.6 and 1.7 on Windows. I have updated the wiki with those results.

There was one area of the tests that I thought were interesting,
because there is a massive regression in 1.6. The tests are with a
working copy that has folders with a couple thousand icons in it. I
mainly wanted to look for problems with a lot of files in one folder
as people on users@ had been complaining. You can see those results
here:

Here are the average checkout/switch times:

         Checkout Switch
1.5: 0:30 0:18
1.6: 7:40 7:15
1.7 2:14 1:46

So while 1.7 has made nice improvements over 1.6, there is still a
huge regression. I would blame it on tree conflicts, but would this
show up in a checkout (maybe because it shares code with update)?
Might be something for someone to look at.
