The graph below shows how much time the light engine was active while generating 10404 chunks:
See "Notice about invalid gen test results" in TECHNICAL_DETAILS.md
for why there is no 1.20 data for this test.
Below is a graph detailing how long light updates took for breaking/placing a block on a large platform at y = 254 down to a large platform at y = 0:
Below is a graph detailing light update times for a simple glowstone place/break:
The results indicate that Starlight is faster for light propagation, but the absolute times indicate that it is unlikely to affect FPS in any situation on the client.
Currently, Starlight's light section management is depended on for both Paper's rewrite of the chunk system (people in the modding space call this "TACS") and Folia's additional changes to that system. In Starlight, light sections are tied directly to ChunkAccess objects.
The light section management prevents most bugs (including performance ones) involving missing/absent light sections, as Starlight assumes that no updates are possible unless the chunk exists. This is why there are basically zero performance or bug related issues with the light section management in Starlight.
This difference in light section management allows Paper's rewrite of the chunk system (which is designed as a solid base for Folia to build on, which adds regionized multithreading to the dedicated server) to greatly simplify and optimize its chunk unload/load logic as it no longer needs to consider any light engine state as there is no light engine state.
The "stateless" property of Starlight allows the chunk system to run light updates / generation in parallel provided the scheduling is done right, see patch "Increase parallelism for neighbour writing chunk statuses" in 1.19 Folia. This is critical to allowing the chunk system to scale beyond 10 worker threads, which is important for dedicated servers with more players to stress chunk generation.
