Benchmarks are implemented using [Google Benchmark](https://github.com/google/benchmark).

To build the benchmarks in this directory you need to set the benchmark
option while configuring the build with meson:

```
meson configure build -Dbenchmark=enabled
```

Then build the benchmark binaries with ninja:

```
ninja -Cbuild perf/benchmark-set
```

Finally, to run one of the benchmarks:

```
./build/perf/benchmark-set
```

It's possible to filter the benchmarks being run and customize the output
via flags to the benchmark binary. See the
[Google Benchmark User Guide](https://github.com/google/benchmark/blob/main/docs/user_guide.md#user-guide) for more details.
