I'm not smart enough to verify the accuracy of this claim, nor exactly what the implications are, but it seems like it might improve performance if fixed.

I took the title from the link, which doesn't exactly match the title on the page. That's why one says 20 years and the other says 15 years.

Heard of that, because you know, a core Duo was a thing. They didnt think anything bigger was possible, some time in the past. But afaik thats pretty old news

Would've been nice of them to compile the kernel with a fix applied to see how much of an impact it has (though even in the post they seem to suggest that it's not that impactful unless you run massive clusters)
