If your Minecraft server is constantly overloading whenever you try to fly through Elytra. It can be caused because of not properly generating the terrain or resources are not enough for handling this kind of load.
This kind of issue can only be fixed with two things first increasing the hardware requirement and second using performance-enhancing mods like Better FPS and Pregen.

Fixes for Server Overload from Elytra Flight.
Optimize Chunk Loading:
Pre-generate Chunks: Using plugins like WorldBorder and Fabric Chunk Pregenerator to pre-generate chunks can significantly reduce the load during gameplay. This means chunks are generated and loaded ahead of time, so players don’t cause a spike in server load by generating new chunks rapidly.
Performance-Enhancing Mods and Plugins:
- PaperMC: A high-performance fork of Spigot, PaperMC offers numerous optimizations for chunk generation and entity management.
- BetterFPS: It will stop useless things from rendering and make the flight smoother.
Optimize Server Settings:
- View Distance: Lowering the view distance can reduce the number of chunks loaded at any one time. This can be adjusted in the server.properties file.
- Tick Distance: Similar to view distance, reducing the tick distance can also help alleviate server load.
Increase Allocated RAM:
- Ensure that your server has enough RAM allocated to handle the load. Increasing the RAM can help manage the increased chunk generation demands.
- Example command to increase RAM allocation:
java -Xmx4G -Xms4G -jar server.jar(adjust the values according to your server’s capabilities).
Upgrade Server Hardware:
- If possible, upgrading your server’s hardware, especially the CPU and RAM, can provide the necessary resources to handle high-speed elytra flight without issues.
