Minecraft Java Edition Server – Why TPS Drops When a Player Joins the Server

minecraft-java-editionminecraft-java-edition-server

Every time someone joins my Minecraft Server the tps drop to 14-16 tps instead of 20 and I don't know why.
Anyone an idea why that is? A plugin?
I use paper 1.16.1 v.6 and I only have Open Inventory, Armored Elytra and Redye as plugins but I use datapacks.
I run the server on a raspberrypi 4gb model B with 2524mb of ram.

According to this Raspberry Pi Minecraft V1.12 Server – Excellent Performance Guide blog, even a Raspberry Pi 4 is not very well suited as a Minecraft Server.

Should you try this?

Let me answer a big question right off the bat. Should you buy a Raspberry Pi just to run it as a Minecraft server? Absolutely not. If you just want to run a Minecraft server, especially one with more than a few people, you are much better off buying a realms subscription or one of the many dedicated Minecraft server options.

A few paragraphs later, the author describes their own setup, which includes a Raspberry Pi 4.

One of the reasons appears to be storage speeds:

Second question: Do you have fast Raspberry Pi storage? Because this tutorial will overclock your SD port from 50hz to 100hz. (Update: Since I wrote this article solid state storage has gone down so much in price that it makes much more sense!) If you have a good SanDisk A1 Class 10 card you should have no problems. However, although the risk is minimal, there is some risk of SD card corruption if you don’t have a high quality card. I am not responsible if your card dies, your Pi explodes, your house gets hit by a meteorite, or anything else that happens! This is solely at your own risk! These are very common overclocks though and the risk is minimal, but you have been warned!

What you can do to fix this

If using a dedicated server (or even a PC) is out of the question, you could try and follow the performance guide linked above. For Minecraft Server 1.14 or newer, you can try this newer guide instead.

CoreProtect is multi-threaded. Bukkit isn't. You have a dual core processor.

What this means is that although Bukkit will be restricted to a single core, CoreProtect can do all file logging on the second core.

This means that server performance will not be impacted at all when using CoreProtect.

Minecraft – Terminal script for Minecraft server autosave

My recommended solution for this kind of thing tends to be "Use The System!".

If you have the option, enabling Time Machine from system preferences to create a full disk backup every hour is usually a good idea, and if you don't have the opportunity, you might want to consider getting an external disk and implementing that approach.

If that is completely out of the question for whatever reason, the alternative is using cron.

Setting up the interval running is easy enough, a simple man crontab should give you the information you need on that; but having a script to actually do the backup might be useful:

#!/bin/sh
cd ~/Desktop/MinecraftServer # or the path to your minecraft server directory
rm -rf world.bak
cp -r world world.bak

Save this as a "minecraft_server_backup.sh" and chmod +x it.

This particular script only keeps the most recent backup, and additionally, it doesn't actually check if the server is running before making a backup.
