+## Benchmarks
+
+We provided some benchmarks for zend-stdlib in the folder [/benchmark](/benchmark).
+We used [athletic](https://github.com/polyfractal/athletic) framework to write the benchmark tests.
+You can execute the benchmarks running the following command:
+
+```
+vendor/bin/athletic -p benchmark
+```
