More performance graphing

Venkatesh Srinivas sent along a graph of his nmalloc testing that shows mysql threading performance on DragonFly, from slightly over a year ago.  Both graphs were done on a 4-core system, though I don’t know if the specs are comparable, so the curve is important.  Look at the just-posted curve for comparison.  That’s how much things have improved.

In fact, here’s a cheesy overlay, cropping the more recent results and laying the old ones on top of it.  The black lines are the year-ago performance, and the colored lines are the performance now.
