Fedora 36 is releasing this morning as what is yet another release in recent times of being a very robust and bleeding-edge yet stable and reliable Linux distribution. I've already been running Fedora Workstation 36 and Fedora Server 36 snapshots on various systems in my benchmarking lab and this release has proven to be quite solid while adding new features and polish on top of the excellent Fedora 35...

In the absence of the BUS1 in-kernel IPC mechanism that appears stalled that was started after the failed KDBUS effort, Dbus-Broker has been taking off as the high performance, reliability-enhanced Linux message broker in user-space retaining compatibility with the reference D-Bus implementation...

Last month an AMD engineer began posting Linux kernel patches so the kernel prefers the MWAIT instruction over HALT for lowering the CPU idle exit latency. Preferring MWAIT over HALT has been something Intel CPUs on Linux have preferred going back to the Core 2 days and indeed with modern AMD CPUs there is significant advantages to lowering the exit latency in doing so for the idle code. This morning the latest iteration of the work was posted...

With my Ubuntu 22.04 LTS benchmarking thus far it's been focused on shiny and exciting high-end hardware, the latest flagship desktop processors, and interesting old hardware comparisons. But what about Ubuntu 22.04 LTS performance on recent but mature hardware platforms? For this round of testing I am looking at the Ubuntu 20.04 LTS versus Ubuntu 22.04 LTS performance on AMD Ryzen and Intel Core industrial PCs from OnLogic. Especially in the case of AMD Ryzen "Renoir" there is still more performance being squeezed out of this new Ubuntu long-term support release.
