This test examines if checking for a feature being inside the visible
extent before rendering it has an impact on performance. Make sure that

console after running this test (hit F12) to see the results.

After the performance test, you can drag around the map to see how the new
vector rendering feels where features get rendered only when they are visible
inside the map extent.
