            <title>[BDS-18479] Problem with spawn rate mobs, and frequent drop in tick speed rate</title>
                <link>https://bugs.mojang.com/browse/BDS-18479</link>
                <project id="11700" key="BDS">Bedrock Dedicated Server</project>
                    <description>&lt;p&gt;On our server, where we play, there are often problems and difficulties with the appearance of mobs, as our server is quite popular and it plays 20+ players, there are very few mobs, only with a small number of players on the server you can see the appearance of mobs, pay attention to this and increase the spawn speed, we have BDS.&lt;/p&gt;

&lt;p&gt;Also, for unknown reasons, the tick rate (TPS) becomes very low. Optimize the BDS, because it&apos;s just awful, and the provided core turns out to be just disgustingly unoptimized and somehow made something.&lt;br/&gt;
Server uses:&lt;br/&gt;
Windows dedicated server: Ryzen 9 5950X, 128 GB RAM, NVME SSD&lt;br/&gt;
Also, others have asked to add that your single-threaded performance is just laggy, and can&apos;t handle a huge number of players at once.&lt;/p&gt;</description>

&lt;p&gt;It only occur on Bedrock Dedicated server? Can you verify CPU/RAM usage when this issue occur? Video from client perspecitive would be helpful, so if you can please recoed it and upload it here. If it exceeds file size limit you can use OneDrive or similar file hosting service and share link.&lt;/p&gt;
