LagFixer

LagFixer helps improve server performance by optimizing the Minecraft engine.
While the paper itself is well optimized, some of its functions still require improvement. It won’t fix all lag by itself, but it can noticeably reduce it when used alongside well coded plugins and a solid server setup. It is not intended to resolve issues caused by low quality or poorly configured plugins.

🛡️ Privacy & Data Collection

This plugin sends error reports, Spark profiler data and bStats metrics to the author's server solely for plugin optimization and finding new performance improvements for your server. Enabled by default. Disable error reporting & Spark via main.errors_reporter: false and bStats via main.bStats: false in config.yml.

⚡ Requirements & Compatibility

Server: Bukkit/Spigot/Paper, hybrid Forge, etc.
