What are the best settings for a private server to reduce lag?

Reducing lag on a private Valheim server requires optimizing both server settings and in-game mechanics. Lag can be caused by high player counts, excessive world modifications, or inefficient server configurations. To ensure smooth gameplay, start by setting up your server with the right hardware and software. A dedicated server with sufficient RAM (at least 8GB) and a stable internet connection is essential. If you''re hosting locally, ensure your PC meets the game''s recommended specifications and close unnecessary background applications.\n\nNext, configure your server settings to prioritize performance. In the server configuration file (start_headless_server.bat), adjust the `-world` and `-password` parameters to ensure proper world loading and security. Use the `-public 0` flag to keep the server private, reducing the risk of unauthorized players joining and increasing server load. Additionally, set a reasonable player limit (e.g., 6-10 players) to prevent overcrowding, which can strain server resources.\n\nIn-game, manage world modifications to reduce lag. Avoid excessive terraforming, as each change to the terrain generates data that the server must process. For example, flattening large areas in the Meadows or Black Forest biome can create significant lag over time. Instead, build structures on natural terrain or use minimal terraforming. Similarly, limit the number of active fires, torches, and smelters, as these objects continuously update and consume server resources.\n\nOptimize your base design to minimize lag. Large, sprawling bases with many interconnected structures can strain the server. Instead, create compact, efficient layouts with separate zones for crafting, storage, and farming. Use stone or wood materials sparingly, as excessive building pieces can increase server load. For example, in the Plains biome, build smaller outposts rather than massive fortresses to reduce the number of objects the server needs to track.\n\nRegularly maintain your server to prevent lag buildup. Clear out unused items, such as dropped resources or abandoned structures, to free up server memory. Use the in-game console command `removedrops` to delete all dropped items in the world. Additionally, periodically restart the server to clear cached data and refresh performance. This is especially important after long play sessions or major world changes.\n\nFinally, consider using mods or plugins to enhance server performance. Mods like Valheim Plus allow you to tweak server settings, such as reducing the draw distance or disabling certain particle effects, to improve performance. However, ensure all players on the server have the same mods installed to avoid compatibility issues.\n\nBy following these steps, you can create a lag-free private server for Valheim. Focus on optimizing server settings, managing in-game mechanics, and maintaining your world to ensure a smooth and enjoyable experience for all players.
