I find it interesting that the processor usage is (head tests, eval tests, body tests) in that order. I would normally expect headers to be no larger than the body in most cases. This implies that either my assumption is wrong, or head tests are more complex, or there are more head tests than body tests.
It might be interesting to know which of those was the case, as well as knowing average head test time and average body test time. I guess I'm not surprised eval tests are heavy hitters, since I would expect them to be more complex than relatively simple re's. But the percentage suggests that it could be a fruitrful area for performance increases.
