Just FYI, I remember that the last session of the "Kernel Testing &
Dependability MC" [1] at the Linux Plumbers Conf 2026 in Tokyo was related to
this topic. It was titled "A fast path to benchmarking", and it discussed the
new OSS tool named "fastpath" [2], quote,

   "Fastpath is a command-line tool specifically designed for monitoring the
    performance of the Linux kernel by executing structured performance
    benchmarks on a diverse range of hardware platforms."
