I suppose it will show some improvement but fail to get performance anywhere near 2.4 -- at least that's what my own tests found. I've been working on a break-down of where we're losing it. Bottom line: It's not simply a price we pay for feature X or Y. It's all over the map, and thus no single patch can possibly fix it.
