I think this is a misunderstanding. This isn't going to result in generalized performance improvements. It's a general pessimization. But it seems extremely likely to facilitate specific performance fixes that will make a huge difference to users who are suffering from particular performance problems. This should benefit users in practice to a much greater extent than it hurts.

Hopefully. ;)

Like Brendan said, "once you find a 500% perf win you have a different perspective about the <1% cost." Well the cost may be a little higher than 1%, but point remains.

Thank you. Who cares about a 2% hit on software that runs 0.001% of the time = the vast majority of software. Performance is ALL about bottlenecks and critical sections. Which you can't do anything about if you don't even know where they are.
