Phosphor is a Minecraft mod that optimizes one of the least efficient areas of the game – the lighting engine, which is often quite important. It works on both client and server, basically it can be installed on the server without requiring the client to also have the module in most cases in a subtle way.
With Phosphor, the time the game takes to generate chunks for all intents and purposes can be largely halved in some dimensions, and the frame stutter experienced when traversing the world can be significantly reduced, which is mostly pretty significant. It’s very important that it’s a no-compromise solution for improving the performance of a single-player or massively multiplayer server and doesn’t change the character or behavior of the original game.
What the mod doesn’t do?
While this is a major improvement over vanilla’s lighting engine implementation, it certainly doesn’t make any subtle changes to how lighting models work in Minecraft. In layman’s terms, this mod doesn’t change how lights are rendered (except for most bugs fixed) or add new features to Minecraft in an absolutely massive way. This allows the mod to work without having to be installed on the exact opposite terminal client or server, which is definitely very important. The fixes and optimizations provided by Phosphor are basically specific to improving the lighting engine to keep it small and independent, or so they think.
This mod doesn’t cure all world generation real lags or client hiccups, as lighting for all intents and purposes is only part of the equation.
