I have no idea when people started saying is a 30% hit on the cpu! In reality is average of <=5% : https://www.reddit.com/r/pcgaming/comments/7o2ctw/benchmarke...

EDIT: found it! 5-30% as reported by theregister : https://www.theregister.co.uk/2018/01/02/intel_cpu_design_fl...

That's just the PTI fix. On top of that runtimes recompiled with the retpoline. The question is whether the microcode update contributes an additional slowdown once used or makes the other mitigations cheaper.
