Desktop reports use 50 ms artificial DB delay to emulate real-world load

This demo app is small and fast — under normal conditions all three rendering strategies score similarly on desktop. PageSpeed Insights does not throttle CPU or network on desktop, so it cannot surface the performance differences that matter in production. Adding ?delay=50 to every page injects a 50 ms sleep after each database query, simulating the heavier queries and higher latency of a real-world application. This makes the RSC streaming advantage clearly visible in Lighthouse scores. The 50 ms delay emulates typical database latency and API response times seen in production applications under load.
