            <title>[BDS-16395] High CPU usage when 1 player joins dedicated server UBUNTU</title>
                <link>https://bugs.mojang.com/browse/BDS-16395</link>
                <project id="11700" key="BDS">Bedrock Dedicated Server</project>
                    <description>&lt;p&gt;Hi I am currently running a dedicated server on a 4 core processor running at about 2.4ghz with 8gb of RAM the server runs just fine but as soon as anyone joins and loads in any chunks the servers performance is unusable due to high CPU usage I was hoping someone could help me optimize the performance of this in some manner to where the server can be ready to be used by myself and others&lt;/p&gt;</description>

&lt;p&gt;It would be very helpful if screenshots/video showing cpu usage when issue were attached. If it exceeds file size limit, you can use OneDrive or similar file hosting service and share link.&lt;/p&gt;

&lt;p&gt;This ticket will automatically reopen when you reply.&lt;/p&gt;</comment>
                            <comment id="1114840" author="JIRAUSER657538" created="Wed, 24 Nov 2021 08:28:44 +0100"  >&lt;p&gt;I am running 1.17.41.01 with 2 instances in a VM with ubuntu 20.? Server, 6 cores, 16G RAM. My disk is an SSD. Watching top, my CPU hovers at the 2% mark with no users. When I log into either instance, it spikes to around 3-400% while it&#8217;s loading up the world, then drops to like 30-50% as I &#160;move around.&lt;/p&gt;


&lt;p&gt;How long do you watch your CPU usage? Do you have any historical info for what it looked like? What kind of disk is behind it?&lt;/p&gt;</comment>
