### Profiling the Code
-We use the tool [`benchmark_plugingetset`](../../benchmarks/README.md) to profile the execution time of [YAy PEG][]. The file [`test.yaml`](../../benchmarks/data/test.yaml) serves as input file for the plugin. First we call `benchmark_plugingetset` directly to make sure that everything works as expected:
