+# BigQuery Benchmark
+This directory contains benchmarks for BigQuery client.
+
+## Usage
+From the `google-cloud-php` directory, set up by running `composer install`.
+
+`php tests/perf/BigQuery/Benchmark.php tests/perf/BigQuery/queries.json`
+
+BigQuery service caches requests so the benchmark should be run
+at least twice, disregarding the first result.
