            <title>[MC-5440] 1.4.6 server drop in performance</title>
                <link>https://bugs.mojang.com/browse/MC-5440</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;Server performance dropped drastically when upgrading from 1.4.5 to 1.4.6. The server is running the same mods(updated to 1.4.6 of course). The server is running with 1-2 people at most(it&apos;s a private server). In 1.4.6 the server is constantly running at lvl0 tick ~50ms and the log has &quot;can&apos;t keep up&quot; far too often in it. Another issue that has appeared is &quot;flickering&quot; blocks and laggy behavior(it&apos;s a lan server so the connection isn&apos;t the problem). In 1.4.5 the server would run at around lv0 tick 5-25ms(at most!).&lt;/p&gt;</description>

&lt;ul&gt;
	&lt;li&gt;Any non-standard client/server build needs to be taken up with the appropriate team, not Mojang.&lt;/li&gt;
	&lt;li&gt;Any plugin issues need to be addressed to the plugin creator.&lt;/li&gt;
	&lt;li&gt;This site is for addressing issues related to the base unmodded MineCraft.&lt;/li&gt;
&lt;/ul&gt;
