+## Performance Tests
+
+Some services contained in Google Cloud PHP provide a performance test, to allow
+Google engineers and others to measure the performance of a client library.
+
+Like other test suites in Google Cloud PHP, performance tests are implemented
+using PHPUnit. Due to the memory-intensive nature of many of these tests, however,
+and the time required to run all tests, it is recommended that you use the test
+group feature to run only the tests required at a given time.
+
+Running the tests is easy, once you have cloned the repository and run
+`composer install` to install all required dependencies.
+
+From the repository root, run the following command:
+
+```sh
+$ vendor/bin/phpunit -c phpunit-perf.xml.dist --group=<group-name>
+```
+
+The group name can be identified by opening a test file (i.e.
+`tests/perf/BigQueryTest.php`), and looking for the `@group` annotation found
+immediately before the class declaration:
+
+```php
+/**
+ * @group bigquery
+ */
+class BigQueryTest extends \PHPUnit_Framework_TestCase
+```
