Are volatile reads really free?
Marc Brooker with some good test data:
It appears as though reads to volatile variables are not free in Java on x86, or at least on the tested setup. It’s true that the difference isn’t so huge (especially for the read-only case) that it’ll make a difference in any but the more performance sensitive case, but that’s a different statement from free.
