# Minecraft Lagging Despite RAM – Fix TPS & Performance

Minecraft lag, TPS drops or high MSPT? Paper, JVM flags, view-distance, Chunky & timings – performance guide with troubleshooting.

**Quick answer:** Minecraft lagging despite lots of RAM? Switch from Vanilla to Paper, set equal `-Xms`/`-Xmx`, lower `view-distance` to 6–8 and run a timings report. That often fixes TPS within minutes.

## Common problems this guide solves

    - **Lag despite 8–16 GB RAM** – wrong server software or JVM flags
- **TPS drops / hitches** – entities, redstone or plugins
- **MSPT above 50** – CPU bottleneck or chunk generation

## Step 1: Switch to Paper

Biggest lever vs Vanilla. Setup: [Install server](/en/gameserver/minecraft/installation).

## Step 2: JVM flags

`java -Xmx8G -Xms8G -XX:+UseG1GC -XX:+AlwaysPreTouch -jar server.jar nogui`
RAM guide: [hardware](/en/gameserver/minecraft/hardware-requirements)

## Step 3: server.properties

`view-distance=8
simulation-distance=6`

## Step 4: Pre-generate with Chunky

`/chunky radius 5000
/chunky start`

## Step 5: Timings report

`/timings report`
