Dwwoodsi perf comments

The difficulties I encountered:

• I like to use right click->save link as. This presented a problem with the sourceforge mirror selection pages. Not a biggie.
• I was a little thrown off in the sequence of things; I tried running it from cygwin and it had trouble (lost the results--will try to update this later with specifics). When I asked in the lab, you told me that it could not be done with cygwin. (this was likely reading comprehension failure on my part.)
