+# Running Performance Tests
+
+## Pre-requisites
+The performance tests are based on the IntegrationTestBase class. Follow the instructions to set up the pre-requisites for integration tests [here](../test/README.md#running-integration-tests).
+
+## Run
+The performance tests use BenchmarkDotNet to benchmark performance for input and output bindings.
+
+Run the tests from the terminal.
+```
+cd performance
+dotnet run -c Release
+```
+
+## Results
+The test results will be generated in the BenchmarkDotNet.Artifacts folder.
