I believe, maybe wrongly because there’s a lot of guesswork and uninformed noise going on, that MacOS High SIerra updates may have already addressed the problem.
If so, as far as I can tell from personal experience, whatever Apple did to fix the problem seems to have made no difference to achievable latency figures or anything else. Mid 2014 i7 Retina MacBook Pro running Logic.
MacOS isn’t Windows of course but if Apple can make a patch that’s unobtrusive to users I would expect MS to be able to as well.
As you say, it seems it’s anyone with a seriously big multi-user database or server cloud who’ll see the worst of the consequences. And the people who build the server hardware using what are now known to be flawed chips.
I’d be surprised if some with deep pockets aren’t contemplating suing wither their hardware supplier or Intel. Which in the end might mean Intel get it in the neck.
What amazes me is that something as potentially serious as this goes unnoticed for a decade. At least, let’s hope it went unnoticed by those with malicious intent. It also highlights the risk of building “back doors” into operating systems to allow bypassing their security - if a back door exists, no matter how it’s hidden, someone with ill intent will find it sooner or later.
