kjcamann added a comment to D10480: Implement shared_mutex re: N4508.

I have recently benchmarked this (platform was RHEL 7 and Haswell), and the libc++ version has about twice the latency of a pthread_rwlock for both classes of locking. libc++ is also about twice the latency of the libstdc++ implementation, because it is just a lightweight wrapper around pthread_rwlocks.
