Eh, splashed out for an Optane SSD 800p when I built this box last year, configured it as a disk cache… I have no idea if it accelerates bootup, tho…

I’d like to issue a small clarification here. Technically, the person in the article is not a member of the “core” Clearlinux team.

I’m saying that not because that “makes it less important”. I’m saying that because I’d like people to understand that Intel as a whole is working on ways to improve Linux performance - and that means whether it’s with Clearlinux or without Clearlinux. So it’s actually a really, really positive development.

What Feng did is very impressive and has been asked for many years - his slides are a very good look at the methodology and tools we use.
