If you\u2019ve gone from camping out in a dirt hut with one friend to building an elaborate Redstone creation with ten, it\u2019s probably time to allocate more RAM.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Where_Can_You_Use_This_Method\"><\/span>Where Can You Use This Method?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>There are different ways to host a Minecraft server. To save you time, let\u2019s first talk about where you can and can\u2019t use the method we\u2019re about to outline.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Minecraft_Realms_RAM_Allocation_Is_Automatic\"><\/span>Minecraft Realms: RAM Allocation Is Automatic<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>If you are using <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.minecraft.net\/en-us\/realms\">Minecraft Realms<\/a>, the official Mojang server host, you can\u2019t adjust your RAM allocation\u2014and you don\u2019t need to.<\/p>\n<p>Minecraft Realms were originally hosted on <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.cloudsavvyit.com\/84\/new-to-amazons-aws-heres-what-you-need-to-know\/?tag=hotoge-20\">Amazon Web Services (AWS)<\/a> servers and are now, after a migration following the Microsoft acquisition of Mojang, hosted on Microsoft Azure servers. The whole time Realms has used a dynamic memory allocation system. Your Realms server simply increases or decreases how much RAM it uses without any intervention from the Realms owner.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Minecraft_Hosts_You_Have_to_Pay_for_More_RAM\"><\/span>Minecraft Hosts: You Have to Pay for More RAM<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>If you\u2019re using a commercial Minecraft host you\u2019re usually paying for a specific tier of hardware. In light of that, you can\u2019t just increase your RAM allocation\u2014you have to pay for a higher tier.<\/p>\n<p>Sometimes you can simply pop over to the website and upgrade on the fly, other times you have to submit a support ticket and wait. Check your Minecraft host\u2019s documentation for further information. Though before you rush to pay for more RAM we\u2019d encourage you to read about how much RAM you really need and how you can avoid paying for upgrades by using a better-optimized version of the Minecraft server.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Self-Hosted_You_Can_Adjust_The_RAM_Yourself\"><\/span>Self-Hosted: You Can Adjust The RAM Yourself<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>If you\u2019re self-hosting your Minecraft server on hardware in your home or remotely on leased hardware, you can increase the RAM allocation up to the limitations imposed by the hardware itself and the overhead demands of the host system. Let\u2019s look at how you do so now.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"How_to_Allocate_More_RAM_for_Your_Minecraft_Server\"><\/span>How to Allocate More RAM for Your Minecraft Server<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>There are quite a few variables in your server\u2019s <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/minecraft.fandom.com\/wiki\/Server.properties\">server.properties file<\/a> that set the game mode, the view distance, and more. However, you won\u2019t find any entries for RAM allocation.<\/p>\n<p>Instead, RAM allocation is handled by command-line arguments passed along to the server software during startup. You set the size of the heap, or memory allocation, with the flags <code>--Xmx<\/code> and <code>--Xms<\/code> which specify the maximum and initial heap size, respectively. You can use either megabyte or gigabyte designations like 1024M or 1G with the flags.<\/p>\n<p>Let\u2019s look at an example startup command and break down all the pieces.<\/p>\n<p><code>java -Xmx1024M -Xms1024M -jar server.jar nogui <\/code><\/p>\n<p>In the above command, we call on Java, we specify a starting heap size of 1024M and a maximum heap size of 1024M. The <code>-jar server.jar<\/code> portion simply points Java\u2019s jar archive tool at the server file, and the <code>nogui<\/code> flag stops the server from creating a GUI window. You can take the GUI flag off if you want a GUI window with performance stats, a player list, and a live view of the server log.<\/p>\n<p>If we want to increase the RAM allocation to, say, 2GB, you can simply shut down the server and run it again with increased values:<\/p>\n<p><code>java -Xmx2048M -Xms2048M -jar server.jar nogui<\/code><\/p>\n<p>You may have noticed that we\u2019re not specifying a range, like 512M to 2048M in our commands, but using the same value for the minimum and maximum heap size. Setting the minimum and maximum as the same value sets the heap size to a fixed value which helps avoid performance hits as Java dynamically adjusts the heap size.<\/p>\n<p>You might be curious what h<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>ens if you don\u2019t set the memory allocation flags at all. Java will default to setting a Minimum HeapSize (the least amount of memory it will use) to 1\/64 the physical RAM reported by the operating system and the Maximum HeapSize (the most memory it will use) to 1\/4 the available RAM.<\/p>\n<p>On most systems, this will be far too wide a range (and far too high a maximum value) and it will impact performance. In our discussion of how much RAM is good for a Minecraft server, we touch on the concept of the Java \u201c<a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.cloudsavvyit.com\/10031\/what-is-garbage-collection-and-how-does-it-affect-your-programs-performance\/\">garbage collector<\/a>,\u201d the built-in mechanism Java uses to manage RAM. In short, if you allocate too little RAM the collector runs too often and if you allocate too much RAM, the collector idles for too long and then runs too hard all at once.<\/p>\n<p>Both are bad for performance so you should aim to increase the RAM allocation for your Minecraft server in modest increments, say from 1GB to 1.5GB to 2GB, until you achieve the results you want.<\/p>\n<p>If you\u2019re running the vanilla Minecraft server software and increasing the RAM doesn\u2019t provide increased performance, consider switching to a heavily optimized fork of the vanilla server, like <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/papermc.io\/\">PaperMC<\/a>. In our experience, switching to PaperMC yields performance gains higher than any amount of extra RAM allocation could provide.<\/p>\n<p>Either way, with a few adjustments\u2014be it to the RAM allocation or the server platform you\u2019re using\u2014you should be able to squeeze out the performance you\u2019re looking for.<\/p>\n<\/div>\n<p><script>\n setTimeout(function(){\n  !function(f,b,e,v,n,t,s)\n  {if(f.fbq)return;n=f.fbq=function(){n.callMethod?\n  n.callMethod.apply(n,arguments):n.queue.push(arguments)};\n  if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';\n  n.queue=[];t=b.createElement(e);t.async=!0;\n  t.src=v;s=b.getElementsByTagName(e)[0];\n  s.parentNode.insertBefore(t,s) } (window, document,'script',\n  'https:\/\/connect.facebook.net\/en_US\/fbevents.js');\n   fbq('init', '335401813750447');\n   fbq('track', 'PageView');\n  },3000);\n<\/script><\/p>\n<blockquote><p><strong><span style=\"color: #ff6600;\">If you liked the article, do not forget to share it with your friends.
