👁 PostgreSQL benchmark with settings of Scaling Factor: 100, Clients: 800, Mode: Read Write. Default - High Perf - acpi-cpufreq performance was the fastest.

👁 PostgreSQL benchmark with settings of Scaling Factor: 100, Clients: 1000, Mode: Read Write. Default - High Perf - acpi-cpufreq performance was the fastest.

The PostgreSQL database server is one of the workloads where with ACPI CPUFreq there is a big difference between the performance and schedutil CPU frequency scaling governors.

👁 Memcached benchmark with settings of Set To Get Ratio: 1:10. Default - High Perf - acpi-cpufreq schedutil was the fastest.

For Memcached workloads here are the numbers for trading some performance for the best performance-per-Watt in the Efficiency Mode.

👁 MariaDB benchmark with settings of Test: oltp_read_write, Threads: 128. Balanced Memory Perf - acpi-cpufreq performance was the fastest.

👁 MariaDB benchmark with settings of Test: oltp_read_only, Threads: 128. Maximum IO Perf - acpi-cpufreq performance was the fastest.

For the MariaDB database server, the performance governor with ACPI CPUFreq is very important. Here the balanced memory, maximum I/O performance, and default modes all yielded similar performance.
