Minecraft Aikar's Flags - The Basics.

While Minecraft is an incredibly popular game, it has unfortunately been known to suffer from performance issues, such as lag and choppy graphics. Aikar’s flags are designed to address these issues and make the game run more smoothly.

So, what exactly are Aikar’s Flags?

Aikar’s flags are a set of flags that can be used when running the game. These flags are designed to change certain settings on the JVM that can improve the performance of the game. Some of the flags include reducing the amount of RAM and processor usage, as well as optimizing the game for better performance.

Why would I use Aikar's Flags?

Using Aikar’s flags can be an effective way to improve the performance of a Minecraft server. By reducing the amount of RAM and processor usage, the game will be able to run more efficiently. Additionally, the flags can be used to optimize the game for better graphics performance. This can help to reduce any lag or choppy graphics that may be causing problems for players.

What are the optimal settings for Aikar's Flags?

One of the biggest recommendations for using Aikar’s flags is to make sure that the flags are used in the correct order. Aikar’s flags are designed to be used in a specific order. If the flags are used in the wrong order, then they may not work as intended and could actually cause more performance issues than they solve.

In addition to using Aikar’s flags in the correct order, it is also important to make sure that the correct version of the flags is used. Different versions of the flags may be designed for different versions of the game, so it is important to make sure that the correct version is being used.

For the latest version of Minecraft Vanilla and PaperMC we recommend using:

java -Xms10G -Xmx10G -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40 -XX:G1HeapRegionSize=8M -XX:G1ReservePercent=20 -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=15 -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:SurvivorRatio=32 -XX:+PerfDisableSharedMem -XX:MaxTenuringThreshold=1 -Dusing.aikars.flags=https://mcflags.emc.gs -Daikars.new.flags=true -jar paper.jar --nogui

Finally, it is important to remember that Aikar’s flags are not a cure-all for performance issues. While they can help to improve the performance of the Minecraft server, they should not be used as a replacement for proper maintenance and optimization of the game.
