My poor home server's ancient Xeon processors are about to be even more painfully slow than before. šŸ˜©

A lot of those patches arenā€™t really needed if you ā€œtrustā€ the software that you run. Obviously, some are, but a lot of these are only interesting to exploit in shared environments.

If it ends up in intel-ucode I may not get much of a choice. If it becomes a matter of a BIOS update, then I might just not bother. I don't know which way these things typically go.

Are you sure that your server even uses AVX extensions for performance-critical operations?

Yes. Although in my case it's less of a critical concern and more of an annoyance.
