Linux 7.2 On Threadripper Shows Some Nice I/O Improvements & Faster Poll, Some Regressions

I have begun testing out Linux 7.2 on more hardware following the winding down of the merge window and culminating with yesterday's Linux 7.2-rc1 release. Today's tests are looking at how Linux 7.2 in its early development state is comparing to Linux 7.1 stable on AMD Ryzen Threadripper.

Why this matters
Why now

The testing follows the winding down of the Linux 7.2 merge window and the release of Linux 7.2-rc1, indicating a mature enough development state for performance evaluation.

Why it’s important

Improved Linux kernel performance, especially on high-end processors like Threadripper, directly contributes to better compute efficiency and capability for various professional and enterprise applications.

What changes

Linux 7.2 is showing early signs of I/O and polling improvements on specific AMD hardware, potentially leading to faster and more responsive systems for demanding workloads.
