I was thinking the same. There are many mutexes out there, some are better at certain workloads than the rest. DistributedMutex and SharedMutex come to mind (https://github.com/facebook/folly/blob/main/folly/synchroniz..., https://github.com/facebook/folly/blob/main/folly/SharedMute...) Just like hashmaps, it's rarely the case that a single hashmap is better under _all_ possible workloads.

Yeah.

I should say, though, that if you're on Windows then I have yet to find a real workload where SRWLock isn't the fastest (provided you're fine with no recursion and with a lock that is word-sized). That lock has made some kind of deal with the devil AFAICT.
