Yikes... 48 hours and still going!!

I am not one of the developers, but that doesn't sound right to me.

I wonder if anything like real-time anti-virus checking is adding to the
slowness of things given the large number of file revisions (I am assuming)?

I also wonder if you fired up sysinternals ProcessExplorer (pointed at
svnadmin) and Filemon would show anything useful? These are useful if
you cant run a debugger and step through the source.
