Why is this considered a "bug"? It might be a little slower in some cases, but of the behavior is correct for a set of inputs and outputs, the classification is a stretch.

  It is a bug that costs you extra money. Makes extra revenue for Azure, though, so there's that.

  Correctness bugs are just one type of bug. Performance bugs are another type. The designation of what should be counted as a bug is less clear for performance bugs but if some operation is slower than it could/should be, and if this slowdown is significant enough to matter, and if fixing the slowdown is quite practical then, yeah, I would definitely call it a bug. I have filed many bug reports for performance issues over the years, and many of them have been addressed.

    In the extreme: a computer that runs 0.1% as slow as it's supposed to might as well be crashed.

  Often performance is a feature. In those cases, bad performance is a fault.

  I'd say something unintentional is a bug. Perhaps someone can use this in a DoS attack

> Suggestions: Well, I don’t know the kernel internals, so I might be way off base, but here are some ideas: ... 5. Don't use Windows, especially on cloud server nodes? Seriously, we have known this for decades. Use Windows where you are forced to by your IT department.

  I develop Windows client software and I need to debug and profile that software, so I need to work on Windows. And, the development tools on Windows are excellent so I'm happy to do that. So, I want bugs like this fixed. Also, Linux necessarily has a different set of quirks/bugs/issues so "move off this platform because of this issue" is often not worthwhile

What a dive. It would be so nice to have more talented people like Bruce working on free software too :) (yeah, I know, evilcorps do pay)
