| 97 | + ### Setting CPU Frequency scaling governor to "performance" | ||
| 98 | + | ||
| 99 | + It is recommended to set the CPU frequency to `performance` before running | ||
| 100 | + benchmarks. This increases the likelihood of each benchmark achieving peak performance | ||
| 101 | + according to the hardware. Therefore, run: | ||
| 102 | + | ||
| 103 | + ```console | ||
| 104 | + $ ./benchmarks/cpu.sh fast | ||
| 105 | + ``` | ||
| 106 | + | ||
