Subversion Performance Tracking

Updated the Subversion Performance Graphs.

Import performance has gotten a little quicker this week.  Everything 
else is about the same.

I'm currently investigating tools for tracking IO bottlenecks relative 
to CPU slowdown.  The best tool I've found for gathering this kind of 
information is cachegrind, a version of Valgrind that does performance 
statistics.  There is also a GUI for cachegrind called kcachegrind that 
generates pretty graphs.

Thanks; let us know what you find!

(And don't hesitate to file issues, of course.  I think we're more in
the data-gathering phase regarding performance issues right now.
Excepting really major issues and really easy ones :-), most
optimizations will probably happen after 1.0.  Right now correctness
is the bigger concern.)
