LPClearLag — Smart ClearLag & TPS Auto-Fix for Paper
Every Paper server admin knows the sinking feeling: TPS drops, players start rubber-banding, and the ground is littered with thousands of dropped items nobody will ever pick up. LPClearLag — Smart ClearLag & TPS Auto-Fix for Paper is a lightweight, dependency-free plugin that tackles exactly that problem. Built for Paper 1.21.x and tested on Paper 1.21.11 build 132, it combines scheduled cleanup, intelligent protection rules, and a real-time performance monitor into a single JAR of roughly 50 KB.
If you have been searching for a ClearLag alternative that actually understands modern Minecraft servers, this plugin deserves a closer look. It requires Java 21 or newer, needs no PlaceholderAPI or Vault, and works out of the box after a single server restart.
What Makes LPClearLag Different?
Most ClearLag plugins simply wipe every dropped item on a timer and call it a day. LPClearLag goes further by monitoring your server's health and reacting only when something is actually wrong. Its two-stage TPS auto-fix is the headline feature: when TPS falls below the configured threshold (18.0 by default) for two consecutive checks, the plugin first clears eligible ground items. If performance is still poor after a recheck delay, it removes a configurable percentage of eligible mobs. A cooldown prevents endless cleanup loops, and admins get notified when an automatic fix fires.
Smart Performance Monitoring
The built-in monitor checks server performance every 5 seconds by default. It watches TPS, loaded chunks, loaded entities, and ground items, comparing each against configurable thresholds. Everything can be tuned or disabled, so you are never locked into someone else's idea of "normal."
Protection That Actually Protects
LPClearLag ships with 1,655 item rules and 156 entity rules, and its protection system preserves the things that matter. By default it can keep:
- Valuable items like diamonds, netherite, and shulker boxes
- Named items and named mobs
- Tamed pets and leashed mobs
- Bosses such as the Ender Dragon and Wither
- Entities carrying inventories, like chest boats and hopper minecarts
- Entities with passengers
- Items dropped within the configured grace period
- Entities in excluded worlds or with protected scoreboard tags like keep and no_clear
Mob clearing is percentage-based rather than absolute, so with the default 70% setting, roughly 30% of eligible mobs of each type remain. That keeps your world feeling alive instead of sterile.
Item Age Protection Done Right
Some entities in loaded chunks do not receive regular ticks, which makes traditional tick-based age checks unreliable. LPClearLag tracks the real-world time when an item is first observed, so newly dropped items stay protected for 3 seconds by default even when their Minecraft tick count is frozen. It is a small detail that prevents a lot of angry messages from players who just died and lost their gear to a cleanup.
Commands and Permissions
Everything is manageable in-game. Use /clearlag status to view TPS, MSPT, chunk counts, entity counts, memory, and the next scheduled cleanup. Run /clearlag now for an immediate sweep, or /clearlag toggle item diamond_sword to flip an individual rule without touching the config file. Aliases include /clag, /lagclear, /clear-lag, and /cleanlag. Permissions are granular, with lpclearlag.command available to everyone and lpclearlag.admin covering the rest.
If you prefer a frictionless setup, the foxygame.net launcher makes it easy to grab LPClearLag — Smart ClearLag & TPS Auto-Fix for Paper from its add-on catalog and keep it updated automatically as new Minecraft builds arrive.
How to Install LPClearLag on Your Paper Server
Installation takes under two minutes. Here is the process:
- Download LPClearLag — Smart ClearLag & TPS Auto-Fix for Paper from the official project page.
- Stop your Minecraft server completely.
- Place LPClearLag-1.0.0.jar into your server's plugins/ folder.
- Start the server and let the default config.yml generate.
- Edit plugins/LPClearLag/config.yml to match your server's needs.
- Apply changes with /clearlag reload.
When settings.auto-update-lists is enabled, the plugin appends newly introduced items and entities after Minecraft version updates while preserving your existing comments and formatting. That means you spend less time maintaining rule lists and more time playing.
Final Thoughts
LPClearLag — Smart ClearLag & TPS Auto-Fix for Paper is not a magic wand, and the developers are honest about that: no plugin can fix lag caused by CPU limits, redstone clocks, or chunk generation. What it does deliver is a dependable, configurable safety net against entity buildup, with a performance monitor that acts before players notice a problem. For Paper 1.21.x servers running Java 21, it is a genuinely smart addition to any admin's toolkit. Clean smarter, monitor automatically, and keep your server running smoothly.
