Hytale Server Requirements and RAM Guide

What Hypixel officially publishes

Hypixel is quite clear about the baseline, and just as clear about what it does not guarantee. The useful part is the official minimum and the performance model: RAM is mostly about loaded world area, while CPU is mostly about players and entities being simulated.

What Hypixel deliberately does not publish is an official per-player RAM figure. That omission is sensible. A small group travelling together at 12 chunks can use less memory than fewer players wandering off in separate directions on the default view radius.

One more official detail worth knowing: the server ships with an AOT cache file that shortens boot by skipping JIT warm-up. It helps startup time, not ongoing tick performance, so it does not change the sizing decision.

What actually uses RAM: loaded area, view distance and spread

For Hytale, RAM follows how much world the server has loaded, and that comes down to two questions: how far each player can see, and how much their loaded areas overlap. Hypixel recommends limiting max view distance to 12 chunks for performance and gameplay. The default maximum view radius is 32 chunks, which is a very different memory target.

The chart below is the bit to remember: 32 chunks is not just “a bit more” than 12. Because area grows with the square of the radius, 32 chunks works out to about 7.1 times the loaded area per player compared with 12 chunks. Going the other way, 10 chunks (320 blocks) is about 0.69 times the area of 12, and 8 chunks (256 blocks) about 0.44 times. Hypixel puts it simply: every time you double the view distance, you quadruple the world around each player.

That has two practical consequences:

• Players together are cheaper than players spread out. A group mining or building in the same region shares much of the same loaded area.
• Independent explorers multiply memory use. Each player heading off alone causes the server to hold more chunks, terrain data and nearby world state in memory.

It is also why slot counts mean so little on their own. Two players on opposite sides of the map can be a tougher RAM case than a fuller server clustered around one town.

Set view distance before you buy more RAM

Hypixel’s own recommendation is 12 chunks, which equals 384 blocks. The default and hard limit is 32 chunks, or 1,024 blocks. On a small plan, published host advice often starts even lower, around 8 to 10 chunks, because that cuts loaded area hard with a modest gameplay trade-off: players see less far, distant activity is reduced, and fresh terrain appears nearer to them.

MaxViewRadius lives in config.json and uses chunks, not blocks. Stop the server, edit it, then start again:

{
  "MaxViewRadius": 12
}

How do you know it helped? After a real play session, server stats memory should settle more comfortably, and the bad moments when players split up should be less dramatic.

What actually uses CPU: players, entities and world threads

CPU is a different problem. Hypixel says it is driven by high player counts and entity counts such as NPCs and mobs. That is the active simulation load: AI, movement, pathing, combat, world logic and the work needed every tick to keep the server state moving.

Each world runs on its own main thread and off-loads parallel work to a shared thread pool. That means strong per-core speed matters more than simply buying lots of slower cores. More cores still help background work and multiple worlds, but the core gameplay logic of a busy world can only move as fast as its main thread.

Hytale’s world tick rate is 30 TPS, so the server gets about 33 ms per tick. If world perf shows a world spending most of that budget during ordinary play, you are looking at a CPU problem, not just a RAM problem.

• More players means more movement, more network work and more interactions to simulate.
• More entities means more AI and pathing, especially in mob farms, settlements and busy bases.
• More worlds means more main threads that can become busy at the same time.
• Shared or weak CPU allocation can produce lag even if memory looks fine.

RAM upgrades do not fix a saturated main thread. If the server feels rough even with memory headroom, you need to look at entity counts, world activity and CPU quality. If you need a deeper tuning pass after sizing, this guide on how to fix Hytale server lag goes further into the usual bottlenecks.

Plan RAM is not the same as Java heap

This trips people up all the time. The RAM shown on a hosting plan or on your machine is not the same as the Java heap available to Hytale. The heap is only part of the total memory budget. The JVM also needs memory outside the heap for garbage collection and internal work, and the operating system still needs headroom.

One published host default is to set max heap to 75% of plan RAM. On a 6 GB plan that means about 4.5 GB heap and about 1.5 GB left for overhead and the system. That is a sensible way to think about it.

Hypixel’s wrapper scripts read JVM arguments from jvm.options, one per line. Their example is:

-Xms2G
-Xmx4G
-XX:+UseG1GC

Do not hand Java all available RAM. If you do, the JVM and the OS have no breathing room, which can lead to instability. Go too far the other way and the heap becomes cramped, so garbage collection runs more aggressively. Hypixel explicitly points out that a common symptom of memory pressure is increased CPU usage from garbage collection.

The easy read on this is simple: if memory usage is tight and CPU climbs alongside it, the server may not be “CPU-heavy” in the usual sense at all. It may just be spending too much time cleaning up the heap.

Why published host guidance disagrees

This is the honest part. Host guidance for Hytale does not line up neatly. The same sort of private server might be pointed at 4 GB by one provider, 6 GB by another, and 8 GB by a third.

That disagreement does not mean one of them is lying. It usually means they made different assumptions about:

• the starting view distance, often 12 chunks versus the default maximum of 32
• how much RAM is reserved for heap versus JVM and OS overhead
• whether players stay together or explore independently
• how cautious they want to be on an entry plan
• how much modding or how many extra worlds they expect

It is also why slot counts are such a weak buying signal. If you want the longer version, here is why slots and RAM are priced differently. For Hytale in particular, “8 slots” says almost nothing about loaded area, entity density or view distance.

The useful takeaway is not a fixed number. It is a starting band. Most entry plans on the market still begin at 4 GB, but some providers start at 6 GB or 8 GB because they would rather leave more headroom than argue over the minimum.

A sensible starting point for most rented servers

Using the published host guidance as a band, plus Hypixel’s own explanation of what drives load, this is a practical place to start. These are starting points, not promises, and the choice should move up or down with view distance, player spread, entities, mods and worlds.

There is a pattern here. Start near the low end if people mostly play together at 12 chunks and the server is lightly modded. Start near the high end if exploration apart is common, you want extra worlds, or you know you will be adding content. If you are planning on installing mods on a Hytale server, the safe rule is to go up a tier for heavy mod packs or logic-heavy server mods.

Storage and bandwidth: the part people forget

Hytale leans on CPU and RAM more than most games, but storage and upload still set limits. Storage matters because worlds keep growing and backups duplicate that data. Hypixel gives a useful reference point: an Exploration save of about 5000×5000 blocks is roughly 661 MB, and world data averages about 27 KB per 32×32 chunk. There is no hard world size cap, so “long-running server” and “lots of exploration” usually means “buy extra storage room now”.

That is why the official storage advice is at least 10 GB free, with 20 GB a safe bet for long play, and an SSD strongly recommended. SSD speed will not magically fix a CPU-bound world, but it does help chunk reads, writes, startup and backups feel less clumsy.

Hypixel also publishes bandwidth per player for the worst case: at 192 blocks of view distance, 2 Mbit/s minimum and 4 Mbit/s recommended; at 384 blocks, 4.5 Mbit/s and 7 Mbit/s; at 480 blocks, 6 Mbit/s and 10 Mbit/s. Those are worst-case exploration numbers, measured while travelling at 1.5 times normal speed to load new terrain faster than a player could. Normal mining, building and crafting use much less, and small-map minigames use very little by comparison. Still, the maths is helpful: at 384 blocks, 8 players all pushing into fresh terrain could need up to 56 Mbit/s of server upload at the recommended rate.

That matters more for self-hosting than renting. The server has to send terrain to every player, while client upload stays under 250 Kbit/s. So your home upload can become the real bottleneck well before your local CPU or RAM does.

Mods and extra worlds change the maths

Mods affect both sides of the sizing problem. Extra content, server logic and extended view distances push CPU harder; extra assets, active systems and more loaded chunks increase memory use as well. On top of that, each additional world brings its own main thread, so a multi-world setup can ask for both more RAM and better CPU scheduling.

That is why “same player count” is not a meaningful comparison between servers. A lightly modded single-world server and a heavily customised multi-world server can need very different plans even with the same group size. As a rule, treat heavy mods or several active worlds as a reason to start one tier higher than you otherwise would.

Self-host or rent?

Self-hosting is fine for small private use, but be realistic about what your PC is doing. Hypixel points out that singleplayer is the most demanding scenario because your machine runs the client and the full server simulation together. Hosting on the same PC you play on is close to that problem: game client, server simulation, world generation and networking all compete for the same CPU time, RAM and disk access.

If you want the DIY route, start with our guide to self-hosting a game server, then use our Hytale dedicated server setup guide for the actual server setup. The network piece is straightforward but essential: Hytale uses QUIC over UDP, with port 5520 by default, so home firewalls and router forwarding have to match that.

Renting makes more sense when your home upload is limited, you play on the same PC, or you want stable performance without leaving a machine on all the time. Self-hosting makes sense when the group is small, the hardware is spare, and you are comfortable managing Java, updates and the network side yourself.

Check after a week, then tune or upgrade

Do not judge a Hytale server from an empty lobby or five minutes after boot. Give it a week of normal play, then check it during the busiest session you actually have: exploration, building, mobs, travel and all. The core commands are server stats memory, server stats cpu and world perf. Use entity count and who alongside them so you can match spikes to player spread or a busy world.

Start with the cheapest fix first: lower view distance before you buy a bigger plan. It attacks the biggest RAM driver directly, and because fewer chunks and nearby systems stay loaded, it often helps CPU too. If you want that to happen only when needed, Nitrado:PerformanceSaver, one of the plugins Hypixel recommends from its development partners, lowers view distance automatically under load, with the obvious trade-off that players may notice the horizon shorten during busy moments.

Hytale server FAQ

How much RAM does a Hytale server need?

The official minimum is 4 GB, but real RAM needs depend far more on view distance and how spread out players are than on player count alone. For a small private server at 12 chunks, 4 GB can work, while many friend groups are better starting at 6 to 8 GB. Larger communities, heavier mods or several worlds usually push you into higher bands.

Is 4 GB enough for a Hytale server?

It can be enough for the minimum setup, especially for solo play or two players staying in the same area with view distance kept sensible. It gets tight once players start exploring apart, because loaded area rises quickly and the Java heap is only part of the total plan RAM. Think of 4 GB as workable, not generous.

How much RAM per player does Hytale use?

There is no official per-player RAM figure, and a fixed per-player number is misleading for Hytale. Two players travelling in opposite directions can use more memory than a larger group sharing one base area. Size from loaded world area, entity density, mods and worlds, then verify with server stats after real play.

Does a Hytale server need a fast CPU?

Yes. Per-core speed matters because each world has its own main thread, and that thread handles the core simulation budget for that world. More cores help with background work and multiple worlds, but a weak or overshared CPU can still lag badly even when RAM looks fine.

Can I run a Hytale server on the PC I play on?

Yes, for a small private setup, but it is the hardest case for your hardware because the PC is running both the client and the server at once. That means CPU, RAM, disk and upload are all shared. If sessions start to stutter under load, separating the server from the gaming PC is usually the cleanest fix.
