Thats why they should sell cpus that sacrifice security for speed. I'll take a cpu thats vulnerable to spectre/meltdown if its 20% faster.

At least on Linux it's pretty easy to disable the mitigations: https://linuxreviews.org/HOWTO_make_Linux_run_blazing_fast_(...

I'm not sure how easy it is to disable on Windows though.

Are you sure that they sacrifice speed for security? It's not obvious to me. Hardware fixes are supposed to be fast. That 20% slowdown comes from software implementation (and you can actually disable it).

I wasn't aware that the fixes for spectre and meltdown had no impact on performance.
