1. Ultimate System Optimization#

The first step is enabling the swapfile:

1
fallocate -l 2G /swapfile
2
chmod 600 /swapfile
3
mkswap /swapfile
4
swapon /swapfile

However, I forgot one thing during this step—fstab:

1
apt install arch-install-scripts
2
genfstab -U / > /etc/fstab

Manually editing fstab is difficult and error-prone; long live the Arch way.

Then, modify the swap usage tendency:

1
echo "vm.swappiness=10" | sudo tee -a /etc/sysctl.conf

2. Ultimate Website Optimization#

The easiest way to reduce resource consumption is to use static web pages—and that’s exactly what this blog is.

1
# This is a reference for build.sh
2
#!/bin/bash
3
rm -rf dist
4
npm run build
5
sshpass -p "password" ssh -T root@wtada233.top "rm -rf /var/www/html/*"
6
sshpass -p "password" scp -r dist/* root@wtada233.top:/var/www/html/

Now the server basically only consumes bandwidth.

3. Ultimate Proxy Optimization#

Use minecraftspeedproxy, a lightweight proxy service. You can find it on GitHub.

4. The Main Event: Minecraft!#

1
java -Xms1G -Xmx1G -XX:+UseSerialGC -XX:MaxRAMPercentage=70 -XX:+DisableExplicitGC -XX:OnOutOfMemoryError="kill -9 %p" -jar server.jar --nogui

I’ve used several others before, but this one seems to work best. I recommend installing some optimization plugins and setting max-tick-time to -1 in server.properties to disable the watchdog.

5. Conclusion#

Once set up, the benefits of swap become apparent—don’t listen to the AI nonsense about swap slowing things down. In reality, swap isn’t meant to be used as normal memory; it’s there to prevent out-of-memory crashes. With this setup, it usually only consumes about 5MB of swap, staying below 512MB even under high load. Very stable.
