AmpereOne CPPC CPUFreq Schedutil vs. Performance Governor Benchmarks
Similar to the ACPI CPUFreq and AMD/Intel P-State CPU frequency scaling driver and scaling governor benchmarks and power efficiency comparisons I routinely do on Phoronix, when recently having the Supermicro AmpereOne server in the lab with the 192-core A192-32X processor, I carried out some CPPC CPUFreq schedutil vs
Similar to the ACPI CPUFreq and AMD/Intel P-State CPU frequency scaling driver and scaling governor benchmarks and power efficiency comparisons I routinely do on Phoronix, when recently having the Supermicro AmpereOne server in the lab with the 192-core A192-32X processor, I carried out some CPPC CPUFreq schedutil vs. performance governor benchmarks for curiosity and reference purposes while looking at the performance and power efficiency. With all the AmpereOne A192-32X benchmarks I ran for the CPU comparisons while having the Supermicro ARS-211M-NR R13SPD in the lab for a few weeks, they were as usual for server CPUs done with the "performance" governor. But Ubuntu 24.04 LTS ARM and others default to using the "schedutil" governor out-of-the-box for relying on scheduler utilization data.
