Lightspeed - Launch optimizations

Speeding Up Minecraft Launch

Are you using large modpacks? Are you familiar with painfully long game startup times? The Lightspeed mod was created specifically to solve this problem.

Important Information

Attention: Lightspeed will not be updated for Minecraft/Forge 1.20, as most of its optimizations are already included in these versions (or their equivalents).

Key features:

• Originally developed for version 1.18.2
• Client-side mod, but can also work on servers
• Supports only the last two major Minecraft versions (1.18.2 and 1.19.2)

How Does Lightspeed Work?

Lightspeed is a launch optimization mod that significantly reduces Minecraft loading time when using modpacks. Currently, it decreases startup time by 48-71%.

Working Principles

The mod detects inefficient loading algorithms in Minecraft and Forge and replaces them with optimized versions. Main optimization directions:

• Reducing file system operations
• Parallel processing of suitable processes
• Caching computed results
• Improved data structures

Guiding Principles

To achieve maximum efficiency, Lightspeed follows several key principles:

Efficiency over multithreading - not all players have 12+ core processors, so the mod uses caching and other operation minimization methods.

Minimal intervention - all changes are made with maximum care, without completely rewriting the code.

Compatibility - development goal: compatibility with most existing mods.

Compatibility

The mod has been tested with an extensive list of mods and should work with most popular modpacks. If you encounter compatibility issues, report them via GitHub.

Important Notes

• Optimizations are noticeable only when using several or many mods
• Startup time cannot be reduced to vanilla level (about 40 seconds)
• The mod is in active development, improvements are added gradually

Frequently Asked Questions

Can I use Lightspeed in my modpack? Yes, you can freely include it in your modpacks, indicating authorship.

Which Minecraft versions are supported? Currently available versions for 1.16.5, 1.18.2 and 1.19.2.

Are there any known compatibility issues? No incompatibilities with other mods have been identified so far.

Why is startup still slow? The mod is under development. Also check memory allocation (-XMX) - too low value can slow down startup.
