Apr 26, 2018 · DotRar. each core has 8 threads. No, each core has 2 threads for a total of 8. normally a minecraft server needs 1 thread if I'm not mistaken. It requires 1 logical thread, not 1 physical thread. You can run thousands of logical threads. That server would definitely run your server though. .

Addition: Some people say optifine makes Minecraft use all available cores, some people say it makes Minecraft use 3 cores and some say Minecraft is hard limited to 1 core. I’m specifically talking about 1.8.9. You can assume the game to mostly utilize a single core for main game loop stuff. That includes mobs, blockupdates, random ticks ...

This feature is exclusive to Java Edition.
This page lists the server requirements of the current Java Edition version, 1.20.2.
For a full tutorial on setting up a Minecraft server, please read the installation and configuration guide.
Requirements may change depending on the server software (like the OS), such as using Bukkit and/or mods.
•A Java runtime (JRE), version 8 or higher. JDK contains JRE, so it will work too. As of version 1.17, JRE version 16 is required. For version 1.18, JRE version 17 is required.
•At least 1 GB of RAM allocated for the server to run (-Xmn 128M -Xmx 1G).
•If you are using Windows or a desktop-based Linux distribution, you should have at least 1 GB of additional physical RAM in the computer, so the graphics on the desktop don't become laggy. It is difficult to determine how much RAM is needed because there are many factors to consider such as the number of players on your server and how they interact with the game world. While a player object only requires about 50 to 100 MB of RAM, the server often has to allocate much more memory per player for many different reasons.
•Depending on the specific java version, you may be able to set a "soft max RAM" amount for the server JAR program. The JDK will try to keep memory usage below the soft max, but will allow it to go above it to reach -Xmx if needed. Try -Xmn 128M -XX:SoftMaxHeapSize=1G -Xmx 2G.
•A CPU with good single-core performance. The server (as of 1.14) does use additional cores for other operations, but typically three cores are used at most.

A thread is essentially a measure of CPU power. For example, take the i9-9900K. This CPU has 8 cores and 16 threads. Each of these 16 threads is capable of working on one task, all by itself. So, for example, one thread could be generating a chunk, while another calculates whether a sand block is hovering in the air or not.
Aug 19, 2017 · The most I've seen a Minecraft server use was four threads on my Steam server. Usage was low (~20%), but higher than idle (10%). Note: I don't play Minecraft and just followed a guide on setting up a Minecraft server.
Apr 3, 2023 · Minecraft Java Edition is one of the most horribly optimized games in the gaming history. At least the bedrock edition is what Minecraft really should have been if it were not Microsoft just ruining it. Minecraft was built in the era when PCs only had 2 to 4 cores at most, so multithreading much of a thing back then.

Jiří Vojta. 21 3. I can't directly answer your question, but for your purposes CPU is mostly irrelevant; memory is vastly more important than clock speed. Also, clock speed is much less descriptive than it used to be, due to more specific pipelines and instructions in silicon. Get mostly whatever CPU, focus your research on your memory.
