Why is my server lagging?
Last modified on Dec 13, 2021 in server errors
When experiencing Minecraft server lag it is common to instantly assume that the server company is low quality. However, more often than not the issues are 1 of a few simple things that can be checked in order to get your Minecraft server running as fast and reliably as possible.
The first and most common reason why the multicraft CPU is 100% is plugins. Plugins are an incredibly tricky thing to master. They take time to really hammer out the details of what will and won’t work with your unique server setup and plugin collection. When installing plugins it is first most important to stop and start your server again in an effort to refresh the server and allow the new plugins to take effect in addition to the normal “reload” command. Five times out of ten this is the issue.
When a simple server restart won’t solve your 100% CPU troubles the problem could still be plugins. This time, let’s make sure that the plugins you have are all the right version. Sometimes available but out of version plugins that are too old or too new can cause serious performance issues with your server. If you don’t have experience with a plugin before, always read up on it before including it in your live server.
If all of your plugins are the right version, it could still be plugins! This time we’re gonna check the configuration files of these plugins. This can usually be diagnosed with the console errors being thrown in multicraft. Or manually by going through you config.yml files and server.properties to ensure everything is working as you’d hope. Remember every setup is unique so take your time and think about it. This isn’t just a game, this is a server to run a game. You must manage it appropriately.
If after all this plugin work you are still experiencing lag, then chances are you have either a bad world ( non optimized blocks), a bad internet connection, a bad computer, or the most common of all, server issues. Not enough RAM to run the amount of plugins, world size, and slots you want. It’s true, plugins make a game better. That’s why advanced mod packs like hexxit and Unleashed are so popular. The reality of these collection of plugins though is that they take processing power. Usually more than you would think. Craftbukkit needs at least 2Gb to run and 1.5Gb to run well. If you put 15-20 plugins on it though you’ll stress the CPU to need more space and you’ll top out 100%. This will happen even faster if the slots are filled and you have a lot of players connected. When this happens there are two things you can do. Either go through your plugins and remove the ones you don’t need. Or upgrade your server RAM to handle the awesome server you really want to make.
