The article you posted seems to concentrate on graphics performance which I've not looked at. However I have looked at Intel's boot / container performance in great detail. I'm doing a bit of work improving the performance of qemu and the kernel to match what Intel Clear Linux can do (which is impressive, especially for running containers securely). Unfortunately the Intel kernel is heavily patched with non-upstream patches, and not even patches which could become upstream (they do things like commenting out chunks of code with single line commit messages). There's not really any way we can use the Intel work directly. Also Intel's kernel uses a very cut-down configuration, but Fedora kernel developers would prefer (with good reason) to ship a single kernel image for all use cases, and by necessity that is a "full fat" kernel. So it's a long process. I've proposed a talk about this subject at the KVM Forum 2016 at the end of August.
