Paper vs Spigot: Which Server Software Should You Choose?

When launching a Minecraft multiplayer server, choosing your server JAR is the single most important technical decision you will make. While Vanilla Minecraft runs Mojang's unoptimized default loop, the server community relies on community-developed software forks: Spigot and Paper.

At Parox Cloud, our 1-click Software Changer provides official support for both Paper and Spigot across modern releases (1.21.x) down to classic versions (1.8.8). Below is a direct comparison of their technical architectures.

Overview: The Evolution from CraftBukkit to Paper

• Bukkit / CraftBukkit: The original plugin API and server implementation that popularized server plugins like WorldEdit and Essentials.
• Spigot: A performance-oriented fork of CraftBukkit that introduced basic entity activation ranges, BungeeCord support, and configuration options.
• Paper (PaperMC): A high-performance fork of Spigot engineered to fix tick-lag, improve server responsiveness, optimize chunk systems, and patch game-breaking exploits.

Head-to-Head Comparison Table

1. Chunk Loading and Asynchronous Processing

In Vanilla and Spigot, when a player moves rapidly (e.g., using Elytra, horses, or ender pearls), chunks must be loaded and saved synchronously on the main thread. If a chunk takes longer than 50 milliseconds to load, the main game loop misses a tick, causing your server's TPS (Ticks Per Second) to drop below the ideal 20.0.

Paper completely rewrites the chunk system: It offloads chunk loading, generation, and disk I/O to background worker threads. As a result, exploration has minimal impact on players engaging in combat or redstone elsewhere on the map.

2. Native Anti-Xray Obfuscation

X-ray texture packs and cheat clients (such as Meteor or Aristois) allow players to locate diamond, ancient debris, and netherite veins through walls.

In Spigot, server owners must install external anti-xray plugins, which consume significant CPU cycles. Paper includes a built-in asynchronous anti-xray engine configured directly in paper-world-defaults.yml:

• Engine Mode 1: Hides ores until they are directly adjacent to an air block.
• Engine Mode 2: Replaces hidden stone and deepslate blocks with fake decoy ores in the packets sent to the client, completely neutralizing x-ray clients without performance overhead.

3. Exploit Prevention & Gameplay Stability

Public survival and SMP servers face malicious griefing attempts: piston chunk-ban machines, oversized NBT book data crashes, and sand/gravity block duplication glitches.

Paper proactively patches known duplication bugs and packet overflow vulnerabilities by default, while providing toggles in paper-world-defaults.yml if you run a server where you want vanilla dupes (such as gravity block duping for TNT quarries) to remain enabled.

4. Plugin Compatibility

A common myth is that Paper breaks Spigot plugins. In reality, Paper implements the full Spigot and Bukkit APIs. Any plugin written for Spigot (e.g., EssentialsX, LuckPerms, Vault, WorldGuard, Multiverse) runs out-of-the-box on Paper.

Furthermore, Paper provides modern asynchronous APIs that high-efficiency plugins leverage to execute database queries and chat formatting off the main thread.

When Should You Use Spigot?

Spigot remains useful in specific legacy environments:

• You run an older Minecraft version (such as 1.7.10 or 1.8.8) with legacy plugins that make non-standard NMS (net.minecraft.server) internal calls.
• You specifically require unaltered vanilla mob behavior without any entity culling adjustments.

How to Switch to Paper on Parox Cloud

1. Log into your server at panel.paroxcloud.com.
2. Stop your server using the Stop button in the Console.
3. Take a quick backup under the Backups tab.
4. Navigate to Software / Version Changer and click Paper.
5. Select your target Minecraft version (e.g., 1.21.4) and confirm.
6. Start the server. The panel will automatically download the latest official Paper build.
