For a small Java Edition world, start with 4 GB of VPS RAM; use 6\u20138 GB when you add a meaningful plugin set or light modpack, and move to 8\u201316 GB for larger modpacks or a busy community. The right number depends on the server software, modpack, view distance, CPU, and how much memory you leave for Linux and Java outside the game heap.<\/p>\n\n\n\n<aside class=\"ap-card\" aria-label=\"Buffalo Linux VPS 4 GB (Basic KVM 4)\">\n<span class=\"ap-card__badge\">Best starting point<\/span>\n<div class=\"ap-card__body\"><p class=\"ap-card__name\">Buffalo Linux VPS 4 GB (Basic KVM 4)<\/p><p class=\"ap-card__best\">Best for docker stacks, small Minecraft server, databases<\/p><ul class=\"ap-card__features\"><li>3 vCPU Intel Xeon E5-2699 v4, 4 GB reserved RAM<\/li><li>60 GB SSD (RAID 1), 3 TB traffic on a 200 Mbps port<\/li><li>1 dedicated IPv4, full root, KVM<\/li><li>Debian 12, Ubuntu 24.04, AlmaLinux 9 or Rocky Linux 9<\/li><li>Buffalo, New York (US East Coast, near Toronto\/NYC)<\/li><li>Pay by crypto, UPI or card<\/li><\/ul><\/div>\n<div class=\"ap-card__side\"><p class=\"ap-card__price\">$9.99\/mo <small>USD monthly<\/small><\/p><a class=\"ap-card__btn\" href=\"https:\/\/my.vpslake.com\/index.php?rp=\/store\/buffalo-new-york-basic-kvm-linux-vps\/basic-kvm-4-linux-vps\">Order now \u2192<\/a><\/div>\n<\/aside>\n\n\n\n<h2 class=\"wp-block-heading\">Quick table: RAM by players and mods<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Use this table as a starting budget for one Minecraft Java server on Linux. It assumes sensible view distances, SSD storage, and no other heavy applications. These are planning ranges, not player-slot guarantees: a five-player modpack can need more memory than a 20-player vanilla world.<\/p>\n\n\n\n<figure class=\"wp-block-table ap-table\"><table><thead><tr><th>Server workload<\/th><th>Typical concurrent players<\/th><th>VPS RAM to start with<\/th><th>Practical note<\/th><\/tr><\/thead><tbody><tr><td>Vanilla or lightly optimised server<\/td><td>1\u20135<\/td><td>2\u20134 GB<\/td><td>4 GB is the more comfortable choice if the world is permanent.<\/td><\/tr><tr><td>Vanilla or Paper with plugins<\/td><td>5\u201315<\/td><td>4\u20136 GB<\/td><td>Plugins, entities, and new chunk generation decide whether you need the upper end.<\/td><\/tr><tr><td>Paper with a larger plugin set<\/td><td>15\u201330<\/td><td>6\u20138 GB<\/td><td>Leave room for Java, the OS, backups, and temporary chunk activity.<\/td><\/tr><tr><td>Light or medium modpack<\/td><td>3\u201310<\/td><td>6\u201310 GB<\/td><td>Check the modpack author\u2019s server recommendation before buying.<\/td><\/tr><tr><td>Heavy modpack or busy community<\/td><td>10\u201330+<\/td><td>10\u201316 GB<\/td><td>The pack, world size, automated farms, and CPU speed can matter more than slots.<\/td><\/tr><tr><td>Network or several servers<\/td><td>Variable<\/td><td>16 GB+<\/td><td>Budget RAM per running instance, plus operating-system headroom.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The word \u201cRAM\u201d on a hosting plan is the machine\u2019s total memory. It is not the same as the <code>-Xmx<\/code> value you give Java. On an 8 GB VPS, for example, Paper\u2019s guidance says to reserve roughly 1,000\u20131,500 MB for Java\u2019s non-heap memory and the operating system, so a starting heap around 6,500 MB is safer than assigning all 8 GB to Minecraft. Read <a href=\"https:\/\/docs.papermc.io\/paper\/aikars-flags\/\" target=\"_blank\" rel=\"noopener\">Paper\u2019s Aikar\u2019s flags guidance<\/a> before changing your startup command.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Vanilla vs Paper vs modded Minecraft<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Vanilla is usually the simplest memory case because it has no plugin layer. A large explored world, high simulation distance, frequent exploration, many entities, or redstone-heavy bases can still create spikes, though a small private world does not automatically need 8 or 16 GB.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Paper is a performance-focused server implementation that supports Bukkit-style plugins. It can be a sensible choice when you need moderation, permissions, claims, or other server features, but each plugin adds code and data to load. A plugin that keeps maps, databases, or large numbers of entities active may affect memory and tick time much more than several simple command plugins.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Modded Minecraft needs a different estimate. The loader, mods, generated chunks, automation, and sometimes a separate database all add overhead. Use the modpack\u2019s server instructions first, then add headroom for expected players. \u201cNumber of mods\u201d is only a rough signal: a few large content mods can require more memory than dozens of small utility mods.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Java Edition requires a compatible Java runtime. Bedrock uses different server software, so size it separately.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why too much RAM can hurt<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">More memory helps when the server is actually short of memory. It does not automatically increase tick speed, fix a slow plugin, or compensate for a CPU that cannot finish its work within the 50-millisecond target for a 20 TPS server.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Giving Java an unnecessarily large heap can also make garbage collection less efficient. The server may spend more time managing a large heap, while Linux has less space for file caches and other processes. That is why a correctly sized 4 GB or 8 GB machine can feel better than an oversized plan with careless JVM settings.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Use a simple sizing loop:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n\n<li>Choose a plan with enough headroom for the OS and Java outside the heap.<\/li>\n\n\n<li>Start with the modpack author\u2019s recommendation, or the table above for vanilla and Paper.<\/li>\n\n\n<li>Test with your real world, view distance, simulation distance, farms, and expected peak players.<\/li>\n\n\n<li>Watch memory use and tick performance during exploration, not only while everyone is standing at spawn.<\/li>\n\n\n<li>Increase RAM only when measurement shows memory pressure; investigate plugins, entities, chunk generation, and CPU time when memory is not the bottleneck.<\/li>\n\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">CPU and disk matter more than you think<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">RAM is only one part of a Minecraft server. Chunk generation and simulation create CPU work, while world saves and new chunk reads depend on storage latency. A server can have free memory and still lag during exploration if a core is busy or a plugin is blocking the main thread.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The two settings most readers should understand are <code>view-distance<\/code> and <code>simulation-distance<\/code>. Paper\u2019s <a href=\"https:\/\/docs.papermc.io\/paper\/reference\/server-properties\/\" target=\"_blank\" rel=\"noopener\">server.properties reference<\/a> defines the first as world data sent to each client and the second as the radius in which entities are updated. Raising either increases work around each player, so lowering them moderately can be a better first test than immediately buying more RAM.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Storage also affects the first visit to new terrain and the time needed to save a world. Keep the world on SSD storage, avoid unrelated disk-heavy services, and keep regular backups somewhere separate. A backup protects the world but is not a substitute for enough live disk space.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Using Aikar\u2019s flags without wasting memory<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Aikar\u2019s flags are JVM startup options commonly used with Paper. They are not a magic performance switch and should be matched to the memory available to the machine. The official Paper page warns that Java and the operating system need memory above the <code>Xmx<\/code> value.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For an 8 GB VPS running one Paper server, a conservative starting command can look like this after you have installed the correct Java version and downloaded <code>paper.jar<\/code>:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>java -Xms6500M -Xmx6500M \\\n  -XX:+UseG1GC -XX:+ParallelRefProcEnabled \\\n  -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions \\\n  -XX:+DisableExplicitGC -XX:+AlwaysPreTouch \\\n  -jar paper.jar --nogui<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Follow the Paper version and current Aikar\u2019s flags documentation. Do not copy <code>-Xmx10G<\/code> onto an 8 GB VPS or run multiple servers with the same heap allocation unless the machine has room for all of them.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Picking a VPS size for your Minecraft server<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For most first self-hosted worlds, the Buffalo Linux VPS 4 GB is the sensible starting point. It has 4 GB of reserved RAM, 3 vCPUs, 60 GB of SSD storage in RAID 1, 3 TB of traffic, full root access, KVM virtualization, and a dedicated IPv4 address. It costs <strong>$9.99\/mo<\/strong> and supports Debian 12, Ubuntu 24.04, AlmaLinux 9, and Rocky Linux 9.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Use the <a href=\"https:\/\/vpslake.com\/buy-buffalo-vps\">Buffalo Linux VPS range<\/a> like this:<\/p>\n\n\n\n<figure class=\"wp-block-table ap-table\"><table><thead><tr><th>VPS size<\/th><th>Good starting use<\/th><\/tr><\/thead><tbody><tr><td>2 GB, $5.99\/mo<\/td><td>A very small test world with low expectations and no heavy plugin stack.<\/td><\/tr><tr><td>4 GB, $9.99\/mo<\/td><td>A small vanilla or Paper server for friends; the best general starting point.<\/td><\/tr><tr><td>8 GB, $16.99\/mo<\/td><td>Light-to-medium modpacks, more plugins, or several applications alongside Minecraft.<\/td><\/tr><tr><td>16 GB, $29.99\/mo<\/td><td>A busy server, a large modpack, or a Minecraft instance with substantial growth headroom.<\/td><\/tr><tr><td>32 GB, $54.99\/mo<\/td><td>Several heavier workloads or multiple server instances that you have measured carefully.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The 4 GB plan has 200 Mbps service, while the 8 GB plan has 300 Mbps and the 16 GB plan has 500 Mbps.

During a busy test, check the Java process, free system memory, swap activity, tick time, and the server log. A recurring out-of-memory error, a heap that stays close to its maximum, or repeated allocation failures are stronger evidence for more RAM than a single lag spike.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If memory remains available while TPS drops, check the main thread, plugins, entities, chunk generation, and view or simulation distance. If the server only lags when players generate new terrain, pre-generating important areas and reviewing storage and CPU performance may help more than adding memory. Change one variable at a time so you know what fixed the problem.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">FAQ<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Is 4 GB RAM enough for a Minecraft server?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">4 GB is a practical starting point for a small vanilla or Paper server with a few friends and a moderate configuration. It is not a promise of a fixed player count: a heavy plugin stack, high distances, or a modpack can move the requirement to 6\u201310 GB or more.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is 2 GB enough for a modded Minecraft server?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">2 GB may be useful for a test world or a very light setup, but it leaves little room for Java and Linux overhead. Check the modpack\u2019s server recommendation first; most meaningful modded setups are better planned around 6\u201310 GB and tested with the actual pack.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does more RAM reduce Minecraft server lag?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">More RAM can reduce lag caused by memory pressure, but it cannot fix every lag source. CPU saturation, slow chunk generation, excessive entities, a plugin problem, and high view or simulation distance can all cause poor tick performance while memory is still available.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How much RAM should I allocate to Minecraft on an 8 GB VPS?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Start around 6,500 MB for one Paper server and keep the rest for Java\u2019s non-heap memory and Linux. Adjust after observing real usage, and do not allocate the entire VPS to <code>-Xms<\/code> and <code>-Xmx<\/code>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I run more than one Minecraft server on one VPS?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, but add the heaps together and reserve memory for the operating system and each process\u2019s overhead. Two small servers may fit on a 16 GB VPS, while two modded servers may need much more; measure each workload instead of dividing the advertised RAM evenly.<\/p>\n\n\n\n<aside class=\"ap-cta\" aria-label=\"Choose your VPS size\"><div class=\"ap-cta__content\"><p class=\"ap-cta__eyebrow\">Self-host Minecraft<\/p><p class=\"ap-cta__title\">Choose your VPS size<\/p><p class=\"ap-cta__text\">Start with reserved RAM, full root access, SSD storage, and a Buffalo US VPS you can configure yourself.<\/p><\/div><a class=\"ap-cta__btn\" href=\"https:\/\/vpslake.com\/buy-buffalo-vps\">View Buffalo Linux VPS<\/a><\/aside>\n\n\n\n<script type=\"application\/ld+json\">{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Is 4 GB RAM enough for a Minecraft server?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"4 GB is a practical starting point for a small vanilla or Paper server with a few friends and a moderate configuration.
