+## Performance testing history
+
+See [Github Actions](https://github.com/twcclegg/libphonenumber-csharp/actions/workflows/run_performance_tests_windows.yml) for a history of previous runs, in the logs, you can see the performance results for each method being tested
+
+Below you can see a sample of what the results might look like
+
