Proxmox Virtual Environment (PVE) has taken one of the biggest steps in its history.

Linux error messages are not random warnings or texts intended only for developers.

In the previous article we saw how the scheduler decides which task gets the CPU — so at this point we know how programs get to run. But running isn’t enough: for a program to be useful, it almost always needs to read and store data — its config from /etc, a shared library from /usr/lib, the rows of a database file, the document you’re saving. So the natural next question is: what actually happens when a program opens a file?| Internals for Interns

The classical advice goes that you prefer to keep processes on the same core for as long as possible (without inducing unfairness) so that you can keep their data warm in the caches, and Linux's EEVDF scheduler does a pretty good job of that. What isn't taken into account is making sure processes are arranged across the CPU(s) in such a way that you minimize the number of levels in the cache hierarchy you have to traverse to service accesses to shared memory.| pradyun.net
