Yep. It was mentioned on the original patch’s mailing list discussion, but the cost was thought to be small. Just goes to show again that “intuition” about software perf is generally ~useless. The only way to know is to measure.

I think it’s totally worth it, but I’m biased ;-) Note that the Linux version is currently in private alpha, and not generally available yet. Hopefully soon though!
