Are you tearing your hair out trying to choose a Minecraft Java plugin server? One wrong configuration and your server could lag to death. To let players enjoy your world, you first need to figure out what configuration you actually need. Let's start with "figure out how many people are playing and how many plugins are installed," then list the considerations for dedicated machines and cloud providers one by one. This article combines personal experience and online resources, ensuring you'll have a clear picture after reading.
Understand Your Needs: Number of Players and Plugins
First, you need to know: "How large of a server do I need to run?" The number of online players and the number of plugins are the two most important factors. Imagine that every online player is consuming resources (CPU, memory, etc.). If 50 people are online simultaneously and dozens of plugins are loaded, the server is like a fully loaded truck climbing a steep hill. Not only is the engine (CPU) roaring near its limit, but the cargo hold (memory) is also packed to the brim. Any sharp turn (a sudden burst of player actions or complex plugin calculations) could cause the whole vehicle 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 requires about 0.15GB, and each additional plugin requires about 0.1GB. That is:
Memory ≈ 1 + 0.15 × Players + 0.1 × Plugins (in GB)For example, a server with 50 players and 30 plugins:
Memory ≈ 1 + 0.15×50 + 0.1×30 = 1 + 7.5 + 3 = 11.5 GB. It is recommended to buy at least 12GB or more (cloud servers typically offer 8G, 12G, 16G, 32G, etc.). A little extra won't hurt, but less could lead to "out of memory" crashes.CPU Formula (Cores/Threads): Minecraft servers require high single-core performance, but plugin servers often need multiple cores to share the load. An empirical formula is: at least 1 CPU core (thread) for every 10 active players, with additional cores based on the number of plugins. For example:
CPU Cores Needed ≈ max(1, Players/10 + Plugins/20)For a server with 50 players + 30 plugins: player part 50/10 = 5, plugin part 30/20 = 1.5, total 6.5, round up to 7 cores. Generally, server hyper-threading counts as threads, so buying around 8 cores is very safe. If budget is limited, at least don't go below the integer part of players/10. For core frequency, aim for high clock speed CPUs.
It's worth noting that you may have heard of Folia, a server core branch that requires high multi-core performance and low single-core performance, but I don't recommend using it. It's still in an experimental stage, a path to choose only when you're at your wit's end. Moreover, its ecosystem is poor, and only a small number of server operators use it.
Bandwidth: Minecraft's bandwidth requirements can be estimated as follows:
- Low versions (1.12-) about 0.25-0.4 Mbps per player
- High versions (1.18+) about 0.3-0.5 Mbps per player
A 10M dedicated uplink can theoretically support 15-20 players.
Dedicated Machine
If you plan to buy a machine to host or run at home, that's a physical machine.
CPU Selection: Never fall for E5 or EPYC junk. Many server operators regret choosing these CPUs. Minecraft has too high a demand for single-core performance.
To keep this article from going out of date, I suggest you search for what CPU model suits you, but generally, high frequency 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 baseline (for fast world and data loading), M.2 is preferred, capacity depends on the world size, generally a few tens of GB is enough. Don't consider mechanical hard drives, don't be fooled by their cheapness and large capacity! Be sure to choose a major brand for the hard drive (Samsung/WD/Kioxia/Patriot/Intel), and don't buy second-hand drives (especially mining drives!!!). If you want to experience data saying goodbye to you at any time, you can try.
Cloud Server
The above is about what configuration you need specifically for running an MC server. Once the hardware requirements are calculated, you also need to consider the characteristics of the cloud provider itself. Here's a simple summary of what to look for when choosing a cloud server (a bit like shopping for equipment on Taobao):
Latency and Network Optimization: Since it's for gaming, latency is definitely critical. Prioritize the location of the data center and multi-line coverage. Domestic players generally choose domestic data centers (e.g., Eastern or North China nodes); if you have overseas players, check if the cloud provider has international egress or overseas data centers.
CPU and Memory Performance: Check the configuration and processor type of the cloud provider's instances. Some cloud providers use old hardware with average performance; some use game-server-grade CPUs (e.g., AMD EPYC, Intel Xeon). Be sure to check the CPU frequency and memory size they give you, and whether it meets your calculated requirements. For example, some vendors advertise "single-core 4GHz," which is like putting "running shoes" on your MC server, allowing TPS to soar.
Disk Type: Go for SSD without thinking, but the difference lies in the read/write speed between SATA SSD and NVMe SSD. For game servers, NVMe SSD or high-speed SATA is recommended to reduce lag during world reading and writing. Also, check if there are data backup and snapshot features for quick recovery in case of emergencies.
Management Panel and Control: The panels of different cloud providers vary greatly. A graphical panel is very user-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 up snapshots. In short, buying a cloud server is for peace of mind, so don't always stare at the command line.
Technical Support and Stability: Check the customer support situation; it's best to have someone online 24/7. The probability of a Minecraft server crashing is not low, and you need someone to handle urgent matters. Professional game cloud providers usually have user forums or communities where you can get answers besides searching. Domestic cloud providers often have tickets and technical groups, which may respond faster.
Price and Billing Model: Finally, consider your wallet. Cloud servers are generally billed monthly or annually, sometimes with discounts for annual payment. It's important to choose based on your budget and not 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 more peace of mind in operations, while a cheap one will leave you with no regrets when something goes wrong.
When choosing, also be careful not to be fooled by flashy advertisements: read the configuration clearly, focus on reputation, and service stability is the most important. Products like Jianke Cloud are good, but there are many other big and small vendors on the market to compare and choose. In a word: "you get what you pay for." Peace of mind is more important than saving money when it comes to servers.
