That is way cool, the question is can someone compare the perf on a normal mac/arm application with it on/off?
Presumably its a hit, otherwise they would have just left it on. I guess its more a question of whether its a .5% hit or a 10% hit.
- dragontamer 6y agoIt would be hard to benchmark. Any single-threaded program wouldn't care at all, because you're just plucking values out of store-buffers (aka: store-to-load forwarding) anyway. There needs to be some kind of multithreaded benchmark, maybe a mutex ping-pong or spin lock ping-pong, to really see the difference. Well... hypothetically anyway. It seems like something that's very hard to actually test for.
