Are you using a large modpack? Do you also experience insanely high launch times when using it?
Then my mod "Lightspeed" might be just what you are looking for.

Request: If you notice any issues please report them (on GitHub) - no improvement is worth having any crashes or incompatibility.

💡About

Lightspeed is a launch optimization mod, that aims to significantly reduce minecrafts launch time when using (heavy) modpacks.
At the moment Lightspeed decreases minecraft's launch time by approx. 48% - 62% This mod is still work in progress and all optimizations will be added bit by bit to ensure a stable and slowy getting better experience. To let you track the launch time improvement for every update Lightspeed displays the launch time at the title screen (look at the Images tab).

📜 Motivation

I'm using a large modpack myself that includes 273 mods (Minecraft 1.18.2). Minecraft takes half an eternity to start - even though I have a solid pc setup. An up-to-date computer takes 7 minutes, a setup of 2015 approx. 15 min and a notebook of 2018 even needs more than 20 min to launch minecraft. That's not really good.

🔭 Roadmap

At the moment Lightspeed decreases minecraft's launch time by approx. 48% - 62%. Every future update aims to improve it at least by 10%.
My final goal is that Lightspeed make your launch 3 to 4 times faster than without using it.
Meaning an unoptimized launch of 7 minutes should be reduced to 2 minutes, 15 minutes to 4 minutes and so on.
If you like this mod, I would be happy if you post a comment with your inital launch time and the time achieved by using Lightspeed.

🧭Maxims (Guiding principles)

To ensure that my goal (improved loading times for everyone) is actually achieved, Lightspeed follows or should follow a few guiding principles:

Efficiency over multithreading: Not everyone has a gaming cpu with 12, 16 or even 20 cores. Therefore, Lightspeed relies on caches and other measures to minimize operations wherever possible.
Minimally invasive: Even though Lightspeed is changing existing source code, it's not an completely overhaul or rearrangement of it. Every adjustment takes place with utmost care.
(Ideally) no incompatiblilites: It's my goal that Lightspeed is and will be compatible with almost all mods out there - if you experience any crashes, weird behaviours or other issues please create an issue on GitHub.
Configurability: I'm aware that not all mods can be compatible with Lightspeed. But you can still use Lightspeed by disabling the problematic optimization feature in the config file.

⚗️How it works

Minecraft and Forge are using some ineffiecient or redundant ways to load, hold and process data. I found some of these. I implemented an alternative algorithm per inefficiency and then observed the startup again to verify that the change resulted in the expected improvement. Lightspeed's optimizations will mainly focus on:

reducing file system operations (especially read access)
parallelizing suitable processes
caching computed results and data
improved data structures

🖥️ Test-Setup & Compatibilties

The following section contains all mods that I'm using in my modpack. Which means that all of these mods should be compatible with Lightspeed.

❗Important Notes

The optimizations will only show an effect if you are using several or a lot of mods.
Some future optimizations may directly tweak other mods. If you don't want that Lightspeed directly improve other mods behaviour you can still disable it - but launch times will be better with keeping them activated.
It will probably not be possible to reduce the launch time down or near to vanilla level (about 40 seconds), because in spite of optimizations there is more to do than not using any mods - But I will try my best to retract that statement at some point.

📝FAQ

Questions

Q: Can I use Lightspeed in my modpack?

A: Yes - Feel free to include Lightspeed into your modpack - Remember to give credit and don't claim Lightspeed as your own creation.

Q: Which Minecraft versions are supported?

A: Lightspeed is currently available for 1.18.2. Other version will hopefully come soon - feel free to request a specific version.

Q: Are there any known incompatibilities with other mods?

A: Not yet - most mods should be compatible with Lightspeed. If you are facing any problems when using Lightspeed please create an issue on GitHub.

Q: I'm still facing high launch times. Why?

A: This mod is still work in progress - look at the Roadmap section for more info. Maybe some mods you are using contain inefficient algorithms. Feel free to create an issue on GitHub with your mod list. I will try to profile and to improve it. Another reason might be your maximum memory allocation (via -XMX) - if this value is too low, minecraft will try to free memory more often and this will hurt the launch time.
