Linux 6.9 Drives AMD 4th Gen EPYC Performance Even Higher For Some Workloads

Now that the Linux 6.9 merge window is past I've begun testing out this in-development kernel on more hardware platforms in the lab. While some performance boosts like Intel Core Ultra "Meteor Lake" running faster on Linux 6.9 was to be expected given EPP tuning in the new kernel specific to those SoCs, one of the unexpected delights has been seeing AMD 4th Gen EPYC performance with some nice performance gains over Linux 6.8 stable.
