Huge Intel CPUs security bug may cause up to 30% performance decrease after patching?!

That's reassuring. I guess time will tell what applications get f***** the most by this. Well, this stuff happens. It's not nice but it happens. But that SSD speed decrease gave me goose bumps.

I guess it's a bigger problem for SSD manufacturers because why would you purchase a superfast SSD when the OS can't handle it anyways...

Seems there are some applications that are severely affected by this such as servers:

Yes, but I still think in the majority of cases for desktop use and render farms without virtualization there won't be significant issues. Some disk operations might be somewhat slower, but I don't know if the difference will be that obvious. There is also this:

where the performance impact in actual use cases is quite small.

We ran some tests and the pre-fix render time was 43:19 and the post-fix render time was 45:35. On a mega long render the pre-fix time was 6:40:38 and the post-fix time was 6:43:02. So even with a long running render, the time difference wasn't huge or increasing. Though, I've heard rumblings that DR will be more affected than just single machine rendering. Still haven't tested that yet.

I looked at some 3D rendering test berofe/after fix and 3D rendering is not affected:

But dont know about DR.
