+Performance testing
+*******************
+
+The sample can be used to test the performance of the Wi-Fi connection.
+The performance tuning is done to achieve a trade-off between memory usage and performance.
+
+The overlay file is located at :file:`overlay-zperf.conf` to run the performance test.
+Default build without the overlay is used to memory footprint testing and analysis.
+The overlay should be enabled to run the performance test corresponding to the memory footprint.
