FAQ
General Questions
Q: Will this plugin conflict with other optimization plugins? A: XreatOptimizer is designed as an all-in-one solution and may conflict with similar plugins like ClearLag, Hibernate, or Chunky. It's recommended to use XreatOptimizer alone for best results.

Q: Does this work on modded servers? A: XreatOptimizer is designed for vanilla and Bukkit-based servers. Modded servers (Forge, Fabric) are not officially supported.

Q: Will this affect gameplay or remove player items? A: No. The plugin only removes dropped items after 10 minutes (with warnings), and never touches player inventories, chests, or other containers.

Q: Can I disable the branding messages? A: No. Branding messages are hardcoded and cannot be disabled or modified.

Performance Questions
Q: How much RAM will this save? A: Typically 50-90% depending on configuration. Empty servers see the most dramatic savings (up to 90%).

Q: Does this work on servers with many plugins? A: Yes! XreatOptimizer is designed to work alongside other plugins and can help mitigate performance issues caused by plugin overload.

Q: Will this fix my lag issues? A: XreatOptimizer addresses most common lag causes (entities, chunks, memory) but cannot fix issues caused by extremely heavy plugins or inadequate hardware.

Technical Questions
Q: Does this modify world files? A: No. XreatOptimizer only optimizes runtime behavior and does not modify world save files.

Q: Is this compatible with backup plugins? A: Yes, fully compatible with all backup plugins.

Q: Can I use this with world management plugins (Multiverse, etc.)? A: Yes, XreatOptimizer is compatible with all major world management plugins.
