Hytale server performance and RAM

View distance is what fills a Hytale server’s memory, so the biggest speed-up is setting the maximum view radius to 12 chunks. Start with 4 GB of RAM for a few friends and 6 GB for a bigger group, then watch the graphs on Overview.

How much RAM you need

Hypixel’s minimum is 4 GB. How much you need beyond that depends on players, how far apart they roam, and mods.

These assume a maximum view radius of 12 chunks. With the default of 32, expect to need a lot more.

Wilderack sets Java’s memory limit from your plan, keeping a little back for the system. You don’t need to add -Xmx yourself, and the startup options can’t go past your plan.

The settings that cost the most

View distance

Hypixel calls view distance the main driver of RAM use. Every player keeps the land around them loaded, up to the server’s maximum view radius.

• The setting is MaxViewRadius in config.json, in chunks. One chunk is 32 blocks.
• The default is 32 chunks. Hypixel recommends 12 (384 blocks) for both speed and gameplay.
• For crowded servers, 8 to 10 keeps things smooth.
• Change it with no restart: type /maxviewradius 12 in Console. Players see in their settings when the server has a cap.

Players spread out

Ten players in one town load one area. Ten players exploring in ten directions load ten areas. If your group likes to wander, lower the view radius or add RAM.

Creatures and NPCs

Hypixel says CPU use rises with players and entities: creatures, NPCs and mobs. Big animal pens and spawner farms add up. If the CPU graph is high while RAM is fine, look at entity counts first. IsSpawningNPC in a world’s config.json turns natural spawning off completely, which is only useful for build worlds.

New land

Making new land costs more than loading land that already exists. Expect the server to work harder when players explore far out, especially in the first days of a new world.

Mods

Plugins and packs run on the server. A heavy world generation pack or a busy minigame plugin can cost more than ten players. Add mods one at a time and check the graphs after each.

Restarts

Hytale doesn’t need daily restarts to stay healthy, but a restart now and then clears out memory after a long, busy session.

• In Schedules, use the Daily restart with warnings preset. It warns players in chat 5 minutes and 1 minute before.
• Set the restart step to run only when nobody is online, so it never interrupts a fight.
• A sleeping server skips the restart. It starts fresh when it wakes anyway.

Pick the right region

Hytale sends game traffic over UDP, so distance shows up as lag right away. Pick EU or US East, whichever is closer to most of your players. If your group is split, pick the side where most of them live; a little extra ping is better than a lot for the majority.

Read the graphs on Overview

Overview shows CPU, RAM, players and network for the last 24 hours and 7 days.

• RAM shows what the game uses against your plan. Java holds on to memory and clears it in batches, so a high but steady line is normal. A line pinned at the top while players lag means you need a lower view radius or more RAM.
• CPU spikes along with lag usually mean too many entities, or Java struggling to free memory. Hypixel notes that more CPU from memory clean-up is a typical sign of memory pressure.
• Players next to the graphs shows you when the server is busiest. Schedule restarts outside those hours.

When the server lags

1. Set MaxViewRadius to 12, or type /maxviewradius 12 in Console.
2. Check the RAM graph. If it sits at the top, move to a bigger plan or remove heavy mods.
3. Check the CPU graph. If it is high, cut down big mob farms or spawners.
4. Make sure the server is in the region closest to your players.
5. If one player has trouble and others are fine, the problem may be on their side. See joining is slow or the world never loads.
