Gryaznova" List-ID: Nate, you should note that A: increasing to 80% was my idea, and B: the data from the benchmarks provide no indication that it is a good idea. That said, it is very possible that C: the benchmark is flawed, because the variance is so high that I am suspicious that something is wrong with the benchmark, and D: that the implementation is flawed in some way we don't yet see. All that said, I cannot say that we have anything here that suggests the change is a good change. My intuition says it should be a good change, but the data does not. Not yet.
