 ## Running benchmarks
 
+### Setting CPU Frequency scaling governor to "performance"
+
+It is recommended to set the CPU frequency to `performance` before running
+benchmarks. This increases the likelihood of each benchmark achieving peak performance
+according to the hardware. Therefore, run:
+
+```console
+$ ./benchmarks/cpu.sh fast
+```
+
 ### Running individual benchmarks
 
 This can be useful for debugging a benchmark or doing a quick performance
