Red Hat Enterprise Linux 9.0 Performing Well, Great Benefit To Newer Intel Xeon & AMD EPYC Servers
Overall Red Hat Enterprise Linux 9.0 is in great shape from the testing I've carried out the past few weeks. RHEL 9.0 can deliver meaningful performance improvements especially for recent generations of Intel Xeon and AMD EPYC server platforms thanks to all the open-source upstream improvements in the Linux ecosystem over the past three years. For those bound to using RHEL8, some of these gains are still achievable by making use of Application Streams or similar package maneuvering.
Through this testing Red Hat Enterprise Linux 9.0 has been stable and living up to RHEL's splendid reputation. For this out-of-the-box/default comparison going from RHEL 8.6 to RHEL 9.0 across dozens of different workloads in total, the AMD EPYC 7773X 2P server was about 15% faster and the Intel Xeon Platinum 8380 2P about 6% faster.
