Once two (or more) benchmarks have been executed, compare the results with:
Once two (or more) benchmarks have been executed, compare the results by downloading the [benchmark tools](https://github.com/google/benchmark/tree/master/tools), and then run the following command:

```
# From the build folder
../test/gbenchmark/tools/compare.py benchmarks baseline.json contender.json
```

### CPU Scaling Warnings

Note: If you receive warnings about CPU scaling, you can change the CPU governor with:

```
sudo cpupower frequency-set --governor performance
```
```
sudo cpupower frequency-set --governor performance
```

The previous setting can be restored with:

```
sudo cpupower frequency-set --governor powersave
```
```
sudo cpupower frequency-set --governor powersave
