+### Run Filter Benchmarks
+
+If you are building a fitler benchmark or want to benchmark the performance delta caused when changing the filters, you can run:
+
+```shell
+./hack/run.sh benchmark-filter <filter_class_name>
+```
+
+This will run the benchmarks for the class with `<filter_class_name>`. For example, if you want to run all of the Exact Filter Benchmarks, you could run:
+
+```shell
+./hack/run.sh benchmark-filter ExactFilterBenchmark
+```
+
+Alternatively, if you want to run all of the benchmarks you can run:
+
+```shell
+./hack/run.sh benchmark-filters
+```
+
 ## Code generation
 
 Sometimes, before deploying the services it's required to run our code generators, by running the following command:
