Earlier this week I ran [2]benchmarks of different CachyOS Linux kernel flavors that proved interesting from the performance overhead of their hardened kernel build to various other interesting performancr takeaways. One kernel flavor I hadn't tested though was their build with the BORE scheduler. Given the interest and feedback from Phoronix readers, here is an article focused on looking at the performance of the BORE scheduler for the Linux kernel on CachyOS.

The BORE scheduler is short ofr the "Burst-Oriented Response Enhancer" and is optimized for bursty workloads, which can be great for desktop responsiveness and similar scenarios. [4]The BORE scheduler's GitHub repository describes itself as:
"BORE (Burst-Oriented Response Enhancer) is an enhanced versions of the EEVDF (Earliest Eligible Virtual Deadline First) Linux schedulers. Developed with the aim of maintaining these schedulers' high performance while delivering resilient responsiveness to user input under as versatile load scenario as possible.
To achieve this, BORE introduces a dimension of flexibility known as "burstiness" for each individual tasks, partially departing from CFS's inherent "complete fairness" principle. Burstiness refers to the score derived from the accumulated CPU time a task consumes after explicitly relinquishing it, either by entering sleep, IO-waiting, or yielding. This score represents a broad range of temporal characteristics, spanning from nanoseconds to hundreds of seconds, varying across different tasks.
Leveraging this burstiness metric, BORE dynamically adjusts scheduling properties such as weights and delays for each task. Consequently, in systems experiencing diverse types of loads, BORE prioritizes tasks requiring high responsiveness, thereby improving overall system responsiveness and enhancing the user experience."
On CachyOS, installing linux-cachyos-bore is their default kernel build with the BORE scheduler patch applied.
I hadn't tested this configuration specifically as part of my earlier CachyOS kernel comparison due to time/resource constraints. Given the reader interest and still having the System76 Thelio Major system in the same setup on CachyOS as the prior round of tests, here are the benchmarks with the CachyOS BORE kernel compared to the other kernel flavors across a wide variety of benchmarks.
