Improve Your Forge Modded Server Performance (OLD)


Lag is one of the saddest things that a Modded Server player can experience. This guide will help you improve performance on your server.

Here’s how you can avoid some lag in your server:

—

# Automatic Restarts

Automatic restarts unload heavy chunks that are still loaded on your server and damage your server’s performance.

||| You can set your server to automatically restart at a time when players are not using your server following our [Scheduled Restarts](/en-us/article/scheduled-restarts-shj7m4/) article.

# Using Anti-Lag Forge Mods

Using Anti-Lag Mods can be very dangerous but they can also be used to avoid huge lag on Modded Servers.

||| We recommend using [RandomPatches](https://www.curseforge.com/minecraft/mc-mods/randompatches) on any Forge server you can as it is improving the performance a lot! Note that this mod is available for versions higher than 1.8.

To install them just drag and drop the Mods into your `/mods` directory.

||| [Here](https://help.ggservers.com/en-us/article/how-to-install-mods-on-your-server-1bauy2t/) is our guide for installing mods into your server.

**Some examples:**

* [ `AI Improvements` ](https://www.curseforge.com/minecraft/mc-mods/ai-improvements)
* [ `Lag B Gon` ](https://www.curseforge.com/minecraft/mc-mods/lagbgon)
* [ `BetterFPS` ](https://minecraft.curseforge.com/projects/betterfps)
* [ `VanillaFix` ](https://minecraft.curseforge.com/projects/vanillafix)
* [ `Entity` ](https://www.curseforge.com/minecraft/mc-mods/entity-lagfix-lag-fix)

# Using Client-Side Shaders Mods

Another way to improve performance while you are playing is to use client-side shaders mods.

||| [Here](https://help.ggservers.com/en-us/article/client-side-mods-1f2zfxl/) is our guide explaining about client-side mods and [here](https://help.ggservers.com/en-us/article/how-to-install-mods-into-your-client-1t47nya/) the one explaining how to install them.

|| We recommend using the following two mentioned mods **together** on your Forge client.

* [ `Rubidium` ](https://www.curseforge.com/minecraft/mc-mods/rubidium)

It provides better rendering techniques and many graphical fixes as you can see on the official page mentioned above.

* [ `Oculus` ](https://www.curseforge.com/minecraft/mc-mods/oculus)

It should fully utilize your graphics card when paired with Rubidium mod and it also provides shaders improvements as you can see on the official page mentioned above.

# ️ Pre-Generating Your World ️

The Minecraft world creation is a process based on complex calculations. What is to know is that the world is generated dynamically as you play, meaning that the full world is not created when you start playing but generates more and more as you play.

A good way to reduce lag on your server is to set from the start a radius where you want your players to play/ explore, then use a plugin/ mod to pre-generate the chunks from that zone, so when players will explore that zone the game will just have to load the already existing chunks instead of generating them.

||| We have a guide [here](https://help.ggservers.com/en-us/article/how-to-pre-generate-your-world-1uqqhq6/) that explains how to pre-generate your world, and also gives examples of plugins/ mods for pre-generating your world for nearly any Minecraft version.

###### World Pre Generator Mod

A great mod to use to pre-generate your world on your Forge server is [World Pre Generator](https://www.curseforge.com/minecraft/mc-mods/world-pre-generator). This mod can be used on 1.12.2 or higher versions of Minecraft. Our guide for setting it up and using it can be found [here](https://help.ggservers.com/en-us/article/how-to-set-up-and-use-world-pre-generator-mod-16qg7cr/).

||| [Here](https://help.ggservers.com/en-us/article/how-to-install-mods-on-your-server-1bauy2t/) is our guide for installing mods into your server.

# Changing Dynmap

If you’re using the Dynmap mod make sure to set the resolution to `vlowres` or `lowres` inside the `configuration.txt` and also the render type to `jpg` instead of `png`.

||| [Here](https://help.ggservers.com/en-us/article/how-to-set-up-and-configure-dynmap-1mj0qtk/) is our guide explaining how to set up and use Dynmap plugin.

# Reducing the Server View-Distance

||| [Here](https://help.ggservers.com/en-us/article/how-to-change-your-server-view-distance-1vohoev/) is our guide for changing the server view distance.

**To do that you’ll need to:**

1. Login into your Multicraft Control Panel [here](https://mc.ggservers.com/site/login).

2. Click on `Files` and click on `Config Files`.


3. Click on `Server Settings`.


4. Find `View Distance` and set it to something lower such as `5` or `6`.

The View-Distance uses an equation to determine how many chunks the server-side will load for the players.

* The equation for view distance is: **(2x+1)²**

**E.g.:**
For the default, of 10, should be: **(2*10+1)²** = 21²; 441.

5. Click on ” Save ” and restart your server.

# Upgrade Your Service

Upgrading your service to a server with more RAM or switching to the premium plan may improve your performance. This is especially true on servers that have a lot of plugins or mods that use more RAM.

||| [Here](https://help.ggservers.com/en-us/article/how-to-upgrade-your-service-1yowxis/) is our guide for upgrading your service.

| Please note that you can always upgrade your service any time you want, paying only the difference and not the full price all over again. Without any additional fees or taxes, upgrades take effect instantly. The same goes for downgrade, so when you downgrade, the extra sum will be automatically added to your account credit for future purchases with us.

# Using Fewer Mods

If you’re experiencing huge lag and can’t get more RAM (⚔ POWER ⚔) for your server, you’re able to think and re-check your mods list. It’s suggested to remove additional not necessary mods that won’t affect the server without them.

Remove them from your `/mods` directory using your FTP File Access and restart your server.
