Most people aren't writing C as far as I know. We use Java, C#, Go, Python etc, some lunatics even use Node. We generally don't care if some mutex is 3x faster than some other mutex. Most of the time if I'm even using a mutex which is rare in itself, the performance of the mutex is generally the least of my concerns. I'm sure it matters to someone, but most people couldn't give two shits if they know what they're doing. We're not writing code where it's going to make a noticeable difference. There are thousands of things in our code we could optimize that would make a greater impact than a faster mutex, but we're not looking at those either because it's fast enough the way it is.
