            <title>[MCPE-19964] Massive lag when worlds are over 500mb</title>
                <link>https://bugs.mojang.com/browse/MCPE-19964</link>
                <project id="10200" key="MCPE">Minecraft (Bedrock codebase)</project>
                    <description>&lt;p&gt;When playing a world that reaches over 500mb there is massive lag experienced by the user. This is when graphical settings are on the lower end, and using a well-specced machine. This is most often triggered when travelling by boat, but happens when moving on foot too.&lt;/p&gt;

&lt;p&gt;Suggestion that an advanced option be given to users that allows larger worlds to be held in RAM for those users with enough memory to spare.&lt;/p&gt;

&lt;p&gt;The game doesn&apos;t seem to use the GPU properly either.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Comp specs&lt;/b&gt;&lt;br/&gt;

This is how LevelDB works. Give it some time to defragment the database, and it will eventually stop lagging the game.&lt;/p&gt;</comment>
                            <comment id="372046" author="depressed-pho" created="Wed, 15 Mar 2017 07:22:46 +0100"  >&lt;p&gt;Confirmed on 1.0.4.11 / iPad Pro. When my world bloated up to 420MB it started to lag quite badly, even without any resource packs or shaders.&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;FPS drops when new chunks are getting loaded from save data.&lt;/li&gt;
	&lt;li&gt;FPS drops more severely when you change something in the terrain (and thus causing chunk data to be overwritten).&lt;/li&gt;
	&lt;li&gt;Loading and saving the world sometimes takes more than a minute, and sometimes takes only a few seconds. And when the game takes minutes to close a world, the world file size usually decreases. So I guess this has something to do with LevelDB database compaction.&lt;/li&gt;
&lt;/ul&gt;
