Is there an io-fabric in the world which exceeds 1 microsecond to perform a write transaction ?
Writes on arm64 aren't usually observable from the remote endpoint when
you would expect them to, they can be buffered unless there's an explicit
readback right afterwards (which creates a dependency that the processor
will fulfill)

I don't mean write-combining cache, I mean posted versus non-posted writes which is a feature of the front-side-bus :)
