Are you tearing your hair out trying to choose a Minecraft Java plugin server? A wrong configuration can make the server extremely laggy. To let players enjoy your world, you first need to figure out what configuration you really need. Let's start with 'know how many players and how many plugins' first, then list the considerations for physical machines and cloud providers one by one. This article combines personal experience and online resources, ensuring you'll have a clear idea after reading.

Understanding Requirements: Number of Players and Plugins

First, you need to understand: 'How large a server do I need to run?' The number of online players and the number of plugins are the two main factors. Imagine that each online player consumes resources (CPU, memory, etc.). If 50 people are online at the same time, with dozens of plugins loaded, the server is like a fully loaded truck climbing a steep slope. Not only is the engine (CPU) roaring near its limit, but the cargo hold (memory) is also stuffed full. Any sudden turn (a burst of player actions or complex plugin calculations) can cause the truck to lose control or even break down. To simplify calculations, we can use a formula to roughly estimate memory and CPU requirements:

• Memory formula: We assume a base overhead of 1GB, then each additional player needs about 0.15GB, and each additional plugin needs about 0.1GB. That is:

  Memory Requirement ≈ 1 + 0.15 × Players + 0.1 × Plugins (Unit: GB)

  For example, a server with 50 players and 30 plugins: Memory Requirement ≈ 1 + 0.15×50 + 0.1×30 = 1 + 7.5 + 3 = 11.5 GB. It is recommended to get at least 12GB or higher configuration (cloud servers typically offer 8G, 12G, 16G, 32G, etc.). A bit more won't hurt; less might cause 'out of memory' crashes.

• CPU formula (CPU cores/threads): Minecraft servers have high single-core performance requirements, but plugin servers often need multiple cores to share the load. A rule of thumb is that every 10 active players need at least 1 CPU core (thread), with additional cores based on the number of plugins. For example:

  CPU Core Requirement ≈ max(1, Players/10 + Plugins/20)

  For example, a 50-player server with 30 plugins: simple calculation: player part 50/10 = 5, plugin part 30/20 = 1.5, total 6.5, round up to 7 cores. Generally, hyper-threading counts as threads, so buying around 8 cores is safe. If budget is limited, at least don't go below the core count rounding of players/10. For core frequency, it is recommended to go for high clock speed CPUs.

  It's worth noting that you may have heard of Folia, a server core branch that has high multi-core requirements and low single-core performance requirements, but I do not recommend using it. It is still in an experimental stage, and it's only a route to take when you have no other options. Also, its ecosystem is poor, and only a small number of server owners use it.

• Bandwidth: In this regard, Minecraft's bandwidth requirements can be estimated as follows:

  • Lower versions (1.12-) about 0.25-0.4 Mbps per player
  • Higher versions (1.18+) about 0.3-0.5 Mbps per player

  A 10M exclusive uplink can theoretically support 15-20 players.

Physical Machine

If you plan to buy a machine to host or run at home, that's a physical machine.

• CPU selection: Never fall for the trap of E5 or EPYC 'e-waste' CPUs. Many server owners regret choosing these CPUs. Minecraft has too high single-core performance requirements. To prevent this article from becoming outdated, I suggest you search on your own for which CPU model suits you, but generally high clock speed is the best.

• Memory selection: Note that MC is almost insensitive to memory frequency; capacity is the key. For example, DDR4 or DDR3 is sufficient.

• Hard drive: SSD is the minimum requirement (for fast world and data loading). M.2 is preferred. Capacity depends on the size of the map world; generally a few tens of GB is enough. Do not consider mechanical hard drives; don't be fooled by their cheapness and large capacity! Be sure to choose a big brand for your hard drive (Samsung/WD/Kioxia/Aigo/Intel). Don't buy second-hand drives (especially mining drives!!!). If you want to experience data saying goodbye to you at any time, go ahead and try.

Cloud Server

The above is about what configuration you need specifically to run a Minecraft server. Once you've figured out the hardware requirements, you also need to consider the characteristics of the cloud provider. Here's a brief summary of key points when choosing a cloud server (a bit like shopping for equipment on Taobao):

• Latency and network optimization: Since it's gaming, latency is crucial. Prioritize data center location and multi-line coverage. Domestic players usually choose domestic data centers (e.g., East China or North China nodes); if there are overseas players, check if the cloud provider has international exits or overseas data centers.

• CPU and memory performance: Check the configuration and processor type of the cloud provider's instances. Some providers use old hardware with average performance; some use game-server-grade CPUs (e.g., AMD EPYC, Intel Xeon, etc.). Make sure to see the CPU clock speed and memory size they offer, and whether they meet your calculated needs. For example, some vendors advertise 'single core 4GHz' as if putting 'running shoes' on your MC server, boosting TPS.

• Disk type: Blindly go for SSD, but SSDs differ in read/write speeds between SATA SSD and NVMe SSD. For game servers, NVMe SSD or high-speed SATA is recommended to reduce world read/write lag. Also check if there are data backup and snapshot features for quick recovery in case of emergencies.

• Management panel and control: Different cloud providers have vastly different panels. A graphical panel is friendly for beginners. Check if there is a one-click deployment panel (e.g., Pterodactyl, MCS, etc.), and whether you can easily reinstall the system, manage network ports, or set snapshots. In short, buying cloud servers is for peace of mind, so don't always stare at the command line.

• Technical support and stability: Look at customer support; ideally 24/7 availability. Minecraft servers have a decent chance of crashing, so you need someone to handle emergencies. Professional game cloud providers usually have user forums or communities where you can get answers besides searching Baidu. Domestic cloud providers often have tickets and technical groups, which may have faster response.

• Price and billing model: Finally, consider your wallet. Cloud servers are usually billed monthly or yearly, sometimes with discounts for annual payments. The important thing is to choose based on your budget, and don't just go for the lowest price. As the saying goes, 'You get what you pay for'; a slightly more expensive plan is often stable and reliable, giving you peace of mind in operations, while cheap ones will leave you with no regrets when something goes wrong.

When choosing, also be careful not to be fooled by flashy advertisements: read the specifications clearly, focus on reputation, and service stability is most important. Game cloud products like Jianke Cloud are also good, but there are many other large and small providers on the market to compare. In short, 'You get what you pay for'; in server hosting, peace of mind is more important than saving money.
