Ubuntu 24.04 LTS & Fedora 40 Continue To Trail Intel's Linux Performance Optimizations

Phoronix - Fri, 05/10/2024 - 00:26
While Canonical has been investing more into the performance of Ubuntu Linux and engaged some new performance improvements in Ubuntu 24.04 LTS, it's still not the fastest Linux distribution out there on x86_64 hardware. Similarly, the recently released Fedora Workstation 40 features the brand new GCC 14 compiler and other leading-edge open-source software packages, but there's still more performance left on the table as shown by Intel. Here are some fresh benchmarks looking at how Ubuntu 24.04 LTS and Fedora Workstation 40 are competing with Intel's in-house Clear Linux distribution that offers aggressive x86_64 Linux performance defaults and the best possible out-of-the-box Linux performance on modern x86_64 hardware.
