Ubuntu 22.10 Bringing Some Performance Uplift For Intel Xeon Scalable

12. Září 2022 - 16:00
Now that Ubuntu 22.10 is into its feature freeze and its Linux 5.19 based kernel landed as well as moving to the GCC 12.2 compiler, I've begun testing this forthcoming Ubuntu Linux (non-LTS) release on more systems. For the current-flagship Intel Xeon Platinum 8380 "Ice Lake" processors, Ubuntu 22.10 does deliver some performance advantages over the current Ubuntu 22.04.1 LTS release. However, Ubuntu 22.10 still trails in a distance behind Intel's own Clear Linux platform for the most aggressive out-of-the-box performance.

Linux Sees A New Attempt At Threaded Console Printing

11. Září 2022 - 11:13
As part of the multi-year effort to overhaul the Linux kernel's printk() code there has been much work in recent months around threaded console printing so each registered console would have a kernel thread and console printing would be decoupled from the printk() callers. That work was aimed for Linux 5.19 but then reverted due to troubles. There is now a new implementation in the works...
