            <title>[BDS-17722] Pre-rendered chunks not fully loading in world.</title>
                <link>https://bugs.mojang.com/browse/BDS-17722</link>
                <project id="11700" key="BDS">Bedrock Dedicated Server</project>
                    <description>&lt;p&gt;Since 1.19.30 (and still in 1.19.31 Hotfix) I&apos;ve been seeing a severe performance degradation where chunks do not fully load and remain as empty spaces in the world.&#160; It can take upto a minute for these areas to fully load, sometimes I need to leave the area and return for it to correctly load.&#160; While the chunks are incomplete, the player is also unable to enter that area and is blocked as if hitting an invisible wall.&lt;/p&gt;

&lt;p&gt;I&apos;ve also noticed this performance degradation when exploring and moving around the world too (specifically when using an Elytra) where the player will just stop moving in the world &amp;amp; be prevented from going further.&#160; This worsens the more the player explores or moves around the world through unloaded chunks.&lt;/p&gt;

&lt;p&gt;This is more apparent when logging into the server, as the world can take a long time to load.&lt;/p&gt;

&lt;p&gt;Checking the server load, performance and IO/Network throughput, while these chunks are unloaded, there is very little load on the host and no IO or Network bottlenecks.&lt;/p&gt;

&lt;p&gt;My BDS Server stores all world data on a remote NFS Share, however I have moved the world data to local storage to rule out any networking issues, and this made no difference at all.&lt;/p&gt;

&lt;p&gt;There are no corruption warnings in the terminal output, and the only log entries are the standard player joined/left and auto compaction messages.&lt;/p&gt;

&lt;p&gt;Performance degradation is also the same regardless of platform used to play (PC/Switch/PS4).&#160; Performance on pre-1.19.30 server is absolutely fine.&lt;/p&gt;</description>
