Oh, that’s interesting, but I don’t know whether TLS can affect on these performance. Can we create a silly but a bit possible small benchmark app, which uses JSC APIs as an embedder? Everytime we use JSC APIs, we use JSLock, which uses TLS.
Another fun thing is running locking micro benchmark included in WebKit tree.
Our ParkingLot is using TLS. So it could be affected.
