A Nasty Performance Regression For Some Intel Systems Wound Up In Linux 6.5 Stable

One of the areas in general that tended to regress a lot in Linux 6.5 across multiple applications were video encoding benchmarks, which tend to be quite sensitive to Linux kernel scheduler and power management / CPU frequency scaling changes.
👁 SVT-HEVC benchmark with settings of Tuning: 10, Input: Bosphorus 4K. Linux 6.4.14 was the fastest.
I'm surprised this level of a regression on an Intel Core i9 13900K made it all the way to Linux 6.5 stable.
