            <title>[BDS-748] HUGE performance issues on good dedicated server</title>
                <link>https://bugs.mojang.com/browse/BDS-748</link>
                <project id="11700" key="BDS">Bedrock Dedicated Server</project>
                    <description>&lt;p&gt;This issue concerns &lt;b&gt;1.10.0.7,&lt;/b&gt; but it is not listed somehoh.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;I&apos;m hosting BDS on a rented dedicated server on Ubuntu 18.04.2 minimal server.&lt;/p&gt;

&lt;p&gt;These are my specs:&lt;/p&gt;

&lt;p&gt;&lt;b&gt;CPU:&lt;/b&gt; Intel Xeon Gold 6140 4x &lt;b&gt;dedicated&lt;/b&gt; cores&lt;/p&gt;

&lt;p&gt;&lt;b&gt;RAM:&lt;/b&gt; 16GB&lt;/p&gt;

&lt;p&gt;&lt;b&gt;60GB SSD&lt;/b&gt;&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;We have a decent community, so there are 6 players online on average daily.&lt;/p&gt;

&lt;p&gt;All runs smooth and fine if 2-3 players are online simultaniously, but as soon as 5 players are online at the same time the game is unplayable for everyone until people disconnect again (so it doesn&apos;t get better over time). So playing with even 5 people is a nightmare.&lt;/p&gt;

&lt;p&gt;We thought maybe traveling through the nether or being apart a lot of chunks may be the problem, but we couldn&apos;t really figure it out. Even being in the same chunk causes insane lags.&lt;/p&gt;

&lt;p&gt;I have nothing except the system and BDS installed, so the installation is as raw as it gets.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;The attached image is a screenshot of when &lt;b&gt;4 players&lt;/b&gt; where online at the same time, and the game was purely unplayable.&lt;/p&gt;

&lt;p&gt;But as you can see the average system load is only at 1.73% and just 1GB out of 16GB RAM is being used.&lt;/p&gt;

&lt;p&gt;Also, it doesn&apos;t seem to make any difference what I set in the &lt;em&gt;server.properties&lt;/em&gt; for &lt;em&gt;max-threads&lt;/em&gt;. We&apos;ve run the server for weeks on the default setting (8 Threads) and for another couple of weeks on &quot;0&quot; (which as it says should make BDS try to use all available threads). It doesn&apos;t seem to make any difference. As you can see in the image, pretty much all of the time just only one core out of 4 is being used.&lt;/p&gt;

&lt;p&gt;Most of the time it&apos;s 1 Core at 100%, all other cores at almost 0%.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;I also attached my current &lt;em&gt;server.properties&lt;/em&gt; file.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;We are german players and the server is also in germany, so it shoudn&apos;t be a problem. The server host is also very good with decent hardware and I had no troubles running other server software on servers by this host (&lt;a href=&quot;http://netcup.de&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;netcup.de&lt;/a&gt;).&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;&lt;span class=&quot;image-wrap&quot; style=&quot;&quot;&gt;&lt;img src=&quot;https://bugs.mojang.com/secure/attachment/206267/206267_WhatsApp+Image+2019-04-04+at+22.50.48.jpeg&quot; style=&quot;border: 0px solid black&quot; /&gt;&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&#160; Is my hardware not sufficient? I mean, it must be enough. It&apos;s a Minecraft server.&lt;br/&gt;
Or is the server software just insanely unoptimized so it doesn&apos;t use all the threads it could use.&#160;&lt;/p&gt;</description>

                            <comment id="863929" author="JIRAUSER583989" created="Wed, 16 Dec 2020 07:30:44 +0100"  >&lt;p&gt;@Toba da&apos;Great&#160;and&#160;@Jordon Moss - I am trying to migrate from Windows to a Ubuntu server instance and I am finding that performance is pretty poor on my linux test (12 Cores 8 GB RAM).&lt;/p&gt;

&lt;p&gt;Are you both suggesting that BDS performance on linux vs windows on the same hardware is drastically different?&lt;/p&gt;</comment>
                            <comment id="802854" author="strikerthehedgefox" created="Mon, 7 Sep 2020 20:49:43 +0200"  >&lt;p&gt;Performance is still pretty terrible on Linux. Much worse than Windows, even.&lt;/p&gt;</comment>
                            <comment id="655960" author="ionicecko" created="Mon, 30 Mar 2020 03:34:53 +0200"  >&lt;p&gt;&lt;b&gt;Thank you everyone for the contributions and continued information.&lt;/b&gt;&lt;/p&gt;

&lt;p&gt;Given that the OP is no longer using BDS and can no longer speak to their original issue I&apos;m going to roll this one into &lt;b&gt;&lt;a href=&quot;https://bugs.mojang.com/browse/BDS-2574&quot; title=&quot;1.14+ Linux Performance Degradation&quot; class=&quot;issue-link&quot; data-issue-key=&quot;BDS-2574&quot;&gt;&lt;del&gt;BDS-2574&lt;/del&gt;&lt;/a&gt;&lt;/b&gt; which has been raised to address the major performance regression seen in the 1.14 releases when running on a linux installation.&lt;/p&gt;

&lt;p&gt;I realise this one is older, however the newer ticket has already been raised internally with Mojang and has a tracking number associated.&lt;/p&gt;

&lt;p&gt;If you would like to add a vote and any extra information to the main ticket it would be appreciated. Any information you think is missing from the summary please let me know in a comment.&lt;/p&gt;

                            <comment id="645720" author="patch885959" created="Wed, 11 Mar 2020 19:00:49 +0100"  >&lt;p&gt;@IonicEcko This is definitely still an issue.  I can&apos;t speak for OP.  I have been running it as a second processor on my Windows desktop because the performance night and day different to Ubuntu.   I have also tried updating to the latest kernel for 18.04 just to be sure.   &lt;/p&gt;

&lt;p&gt;@Antoly Sokolov It only partially supports Multi-core.  From what I have read,  chunk loading uses multiple processes.   I have also seen multiple threads created when I enable tickingarea, but I don&apos;t watch it close enough.&lt;/p&gt;</comment>

&lt;p&gt;If only there was a chance to run multicore!&lt;/p&gt;</comment>

&lt;p&gt;Is this still an issue. I regularly have a large number of players on my server and haven&apos;t noticed any issues.&lt;/p&gt;

We implemented a despawn mechanic to reduce mob count. As soon as our player limit reaches around 9 or ten we can&apos;t even walk around.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;
