Reasons Your Minecraft Server Might Be Lagging and have lag issues


1. Plugins (outdated), when your server starts to lag, it could be happening because your using an old version of a plugin, try going through all your plugins and updating them. Even if your server isn't lagging, updating all your plugins will help performance!


2. Plugins (Memory leak), when adding new plugins, don't add them in bulk, add them a few at a time, and let your server run for a while with them, sometimes plugins can leak some memory as they work, meaning, the longer your server is running, the more lag there will become, although this is a rare form of lag (on a large scale), it is sometimes one of the worst ones to fix.


3. Corrupt Worlds, it is possible for certain chunks within Minecraft worlds to become corrupt and have massive lag spikes. It is often caused from certains mods or modpacks that may be buggy and coded poorly. If you notice certain areas of your world are very laggy, try and find out what could be causing it. Some of our customers have had success fixing the world chunk issues by downloading the world to their computer from their Server FTP connection, and loading it into a single player version of the modpack which can fix issues with chunks, and then re-uploading it back to the server. Also loading the world into the program MCEdit you can find corrupt chunks and remove them. If this doesn't work you can try restoring the world from a backup before the corruption occurred. If you don't have backups of your world in multicraft using the backup and restore feature, we keep daily backups of all server files and worlds going back 7 days in the past, if you want us to restore a world backup for you please contact us.


4. Too Many Mods, if you try to run too many mods at once you may run into lag issues. The more mods a Minecraft server is using at once the more Ram and CPU required to host the server without it lagging. Make sure your server has enough Ram allocated to it and consider upgrading the plan for more ram if needed. Also sometimes certain mods can overload, things like too many quarries, too many chunks loaded at once, too many machines, etc, can also cause lag issues. Try to remove any lag machines like this that could be causing problems.
