            <title>[MCPE-22107] Large World File Size and Entity Lag</title>
                <link>https://bugs.mojang.com/browse/MCPE-22107</link>
                <project id="10200" key="MCPE">Minecraft (Bedrock codebase)</project>
                    <description>&lt;p&gt; Seems like world size and entity count is becoming a bigger problem in the latest versions. The latest version I experienced smooth performance in was in around 0.16.0. One of my worlds during 0.16.0 was a whopping 1.2 GB, and surprisingly, the game handled it pretty well, with barely any lag to be noticed. Since the official release updates, &lt;b&gt;a world as big as 50 MB and a chunk with 20+ entities looks like enough to send the game into a crashing mess when trying to load chunks&lt;/b&gt;. My phone is an &lt;b&gt;Android ZTE (Z987) GRAND X MAX +&lt;/b&gt;, and I&apos;ve been using this phone to play MCPE since (I think) 0.7.2, and until the official release updates, the game has been running smoothly. I&apos;m not sure if it&apos;s my phone that&apos;s having trouble running the game, or the game itself.&lt;/p&gt;</description>

I&apos;m pretty sure it is because of chunk keys having x, z coordinates &lt;b&gt;before&lt;/b&gt; the dimension ID and thus chunks for different dimensions interleave in the key space and fragment severely. (See &lt;a href=&quot;https://minecraft.gamepedia.com/Pocket_Edition_level_format&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;Pocket Edition level format&lt;/a&gt;.) I must say this was a bad choice but I doubt devs could change this without breaking all the existing worlds.&lt;/p&gt;</comment>

For example, if I die in the Nether while there&apos;s no lag and respawn in the Overworld, the Overworld will suffer terrible lag.&lt;/p&gt;</comment>
