Please report any issues to our issue tracker.**\n\n## So what is VMP? \nVery Many Players, or VMP for short, is a Forge mod designed to improve general server performance at high playercount \n**without sacrificing vanilla functionality or behavior**.  \nFor the best performance it is recommended to use VMP along with [Lithium](https://modrinth.com/mod/lithium).\n\n## How VMP achieves its performance improvements?\n\n*This list may contain features currently unreleased and only found in development builds*\n\n**Server-side game logic performance improvements:**  \n- Uses area maps to optimize nearby packet sending and player lookups\n- Uses cache to optimize entity trackers, fluid state lookups, ingredient matching and biome lookup\n- Optimizes natural spawning with caches and other tricks\n- Optimizes entity tracking with area maps\n- Optimizes entity iteration for collisions\n- Optimizes ticket propagator using MCUtil from the Paper project (patch licensed under MIT)\n- Makes initial chunk loading async on player login\n- Makes several commands run async **only when issued by a player**\n\n**Client-side game logic performance improvements:**  \n- Makes time source to use built-in Java time source instead of GLFW via JNI calls\n\n**Networking performance \u0026 responsiveness improvements:**\n- Uses our own chunk sending mechanism (optionally with packet-level rate-limiting)\n- Adds packet-level per-player render distance\n- Makes vanilla tcp connections more responsive using packet priority from raknetify  \n  (works best when the server is connected **without reverse proxies such as Velocity and SSH port forwarding**)\n- Mitigates several kinds of bot attacks with split event loops and optimizations\n\n**Other improvements:**\n- Uses AsyncAppender to improve logging performance and keep logging IO off the main thread\n\n**... and more**\n\n## Support\n[Issue tracker](https://github.com/RelativityMC/VMP-forge/issues)  \n[Discord server](https://discord.gg/Kdy8NM5HW4)\n\n## Building and setting up\n_Requires Java 17 or later, both to build it and to use it._  \nUse Git to clone this repository, **do NOT download zip**  \nRun the following commands in the project directory:\n\n```shell\n./gradlew clean build\n```\n\n## License\nLicense information can be found [here](/LICENSE).\n\n\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frelativitymc%2Fvmp-forge","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frelativitymc%2Fvmp-forge","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frelativitymc%2Fvmp-forge/lists"}
