Setting this gamerule to a high number can harm the performance. You can delete all dropped items on the ground with the command /minecraft:kill tick speed: The random tick speed is a gamerule that changes how often certain random events in a world occur (read more here). This can for example happen when you give a player a very large number of items through the /give command. Items: Having many items on the ground can cause performance problems. We do not recommend to keep many mobs (animals or monsters). Mobs: For example, mobs have a big impact on performance. GameplayĪlso during the game there are a few tricks how you can reduce lags.

By the way, the rule that the newer the version the better also applies here. They always contain the latest improvements and corrections. PaperMC is a software which contains several enhancements over the vanilla version to improve performance. Additionally it supports the installation of plugins.Īdmittedly, PaperMC does not solve all problems and the performance is still not outstanding but still worth the switch. You can find the Mojang bug tracker to report performance problems or other bugs here: Use Paper Since 1.17 this feature has been moved to a different command. After that, you can find and download the report here: You can execute that command either in-game or in the console. You can create a debug report with the command: /debug report Since 1.14.4 Mojang recommends creating a debug report and send it to them when you have performance problems so that they can find and fix the causes. The basic performance problem is still present in the newer versions, but will hopefully improve with the newer versions. We recommend to always use the latest version, it contains the latest optimizations and fixes. We've already increased the resources (RAM + CPU) for Vanilla 1.13 and newer servers, but there are still performance problems that cannot be solved with more resources. Unfortunately, this new world format isn't really optimized yet and causes lots of performance problems.


Since 1.13 Minecraft has a completely new world format to enable the new water changes.
