While compare-and-swap is a lot better than a mutex, it's still not free. IIRC a CAS is one (or maybe two) order(s) of magnitude more expensive than a normal store. So a non-threadsafe PRNG should still give you a performance boost compared to the CAS-version. But, as you said, this is all speculation until someone writes some tests... -- !
