  1. UNIQUE FIX FOR NETTY CRASHERS, few rare clients, like GasClient, have NettyCrasher exploits, one type of exploit that doesn't affect the server's TPS but Netty's threads. A NettyCrasher makes Netty's threads busy when a packet gets decoded, so the server crashes and doesn't listen for any packet anymore. LPX is the only anti-exploit having this check without the use of any strange ViaVersion fork or Spigot fork.
  2. Custom Injection and no dependency required, LPX uses a unique way to inject compared to other anti-exploits, this guarantes high performance without the use of Reflections to read packets.
  3. Smooth Packet Limiter, Usually, anti-exploits don't encourage the use of packet limiters because it could cause issues with players having bad connections. LPX has an accurate way to count spam packets and has a fully working VL system to prevent false flags when players lag. If any false is detected, the config can be easily edited to fix false flags.
  4. Printer/Schematica Compatibility, usually packet limiters plugins causes incompatibility issues with this mods, LPX has a very useful automatic system that detects when a player started using printer mode and that guarantees no false kicks. There is also the option to use the API.
  5. Advanced Packet Logger, if your server is attacked with a packet exploit you can log every packet sent from any player to understand what type of exploit did he use and we can fix it in a few days. Packet Logger can be disabled, configured, and doesn't take too much memory because of automatic old file removal.
  6. Easy and detailed configuration, you can edit almost everything while you detect false-flags, you can choose to enable/disable kicks for every check, enable/disable specific checks and change EVERY VALUE used in the code.
