            <title>[BDS-3850] Poor performance with OP hardware</title>
                <link>https://bugs.mojang.com/browse/BDS-3850</link>
                <project id="11700" key="BDS">Bedrock Dedicated Server</project>
                    <description>&lt;p&gt;We Just finished building a dedicated server for our needs.&lt;br/&gt;
CPU: Ryzen 3950X&lt;br/&gt;
RAM: 64GB 3200Mhz 16CL&lt;br/&gt;
Mass Storage: SSD&lt;/p&gt;

&lt;p&gt;As our &quot;lets do something stupid to benchmark it&quot;&lt;br/&gt;
Our final test was to run Bedrock edition server off of it because of it&apos;s superior multithreaded optimizations.&lt;br/&gt;
And it ran like it was hosted from someones phone.&lt;br/&gt;
New chunks and old chuncks were loading very slowly and and it couldn&apos;t even handle 160x160 tnt properly.&lt;br/&gt;
If I do this off of my own i7 3930k, 16GB ram, SSD and Win10home I get much better performance and my CPU usage will be at 100% like it should be.&lt;/p&gt;

&lt;p&gt;With the small scale tnt test, my PC takes 1 min to blow it up, on the dedicated server, it took 10 minutes.&lt;br/&gt;
On paper, even my CPU in 1 treaded performance loses to 2nd gen ryzen by a huge margin.&#160;&lt;/p&gt;

&lt;p&gt;Heck, even Our JAVA server out performed the Bedrock server.&lt;/p&gt;

&lt;p&gt;This is unacceptable.&lt;/p&gt;</description>

                            <comment id="660567" author="ionicecko" created="Tue, 7 Apr 2020 03:48:55 +0200"  >&lt;p&gt;I think you&apos;ve confused the two responses in my comment.&lt;/p&gt;

&lt;p&gt;The quote you&apos;re referencing was in the paragraph directed at Stephen who mentioned he was using an old Xeon chip that was equivalent to an i7-2700. It had nothing to do with your 3950x.&lt;/p&gt;

&lt;p&gt;Ionic&lt;/p&gt;</comment>
                            <comment id="660558" author="greatmcgamer" created="Tue, 7 Apr 2020 03:38:09 +0200"  >&lt;p&gt;Well. you didn&apos;t exactly say &quot;as powerfull&quot; you claimed it to be better&#160;&#160;&quot;its far more capable than your chip&quot;&lt;br/&gt;
As within context of my post, my chip is the Ryzen chip, as within context we are talking about my OP server rig, not my personal gaming rig.&lt;/p&gt;

&lt;p&gt;And&#160;&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;&#160;seems to align with what I saw with my linux machine.&lt;/p&gt;</comment>
                            <comment id="660105" author="ionicecko" created="Mon, 6 Apr 2020 04:53:07 +0200"  >&lt;p&gt;No? Where did I say that?&lt;/p&gt;

&lt;p&gt;Edit: Turns out, even if I did, it wouldn&apos;t have been as crazy as you&apos;re insinuating. See below single core comparison and my previous comments about multi-threading.&lt;/p&gt;

                            <comment id="659645" author="ionicecko" created="Sun, 5 Apr 2020 11:12:07 +0200"  >&lt;p&gt;&lt;a href=&quot;https://bugs.mojang.com/secure/ViewProfile.jspa?name=GreatMCGamer&quot; class=&quot;user-hover&quot; rel=&quot;GreatMCGamer&quot;&gt;GreatMCGamer&lt;/a&gt; - We&apos;re tracking a performance hit in 1.14 for Linux against &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;. You should find that running the same server on Windows provides far better performance on the current version.&lt;/p&gt;

&lt;p&gt;As far as multi-threading goes, while BDS will spin up threads for &lt;em&gt;some&lt;/em&gt; workloads the main game loop still runs on a single thread. For example below is an example of my server with 3 active players and a huge villager hall (which has a huge CPU impact at the moment). The highlighted core is the main thread.&lt;/p&gt;

&lt;p&gt; &lt;span class=&quot;image-wrap&quot; style=&quot;&quot;&gt;&lt;a id=&quot;279090_thumb&quot; href=&quot;https://bugs.mojang.com/secure/attachment/279090/279090_BDS-CPU-WinServer19.png&quot; title=&quot;BDS-CPU-WinServer19.png&quot; file-preview-type=&quot;image&quot; file-preview-id=&quot;279090&quot; file-preview-title=&quot;BDS-CPU-WinServer19.png&quot;&gt;&lt;img src=&quot;https://bugs.mojang.com/secure/thumbnail/279090/_thumb_279090.png&quot; style=&quot;border: 0px solid black&quot; role=&quot;presentation&quot;/&gt;&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;Because we&apos;ve already raised poor linux performance with the devs under &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; I&apos;m going to ask that this be duplicated into that.&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;https://bugs.mojang.com/secure/ViewProfile.jspa?name=Uncle+Fungus&quot; class=&quot;user-hover&quot; rel=&quot;Uncle Fungus&quot;&gt;Uncle Fungus&lt;/a&gt; - If you believe you&apos;re having issues you will need to open your own report however I would suggest checking your individual cores before doing so. The i7 2700k has a far lower capacity than the i7-8700 shown in my picture and as you can see, with 3 people online and a villager trading hall my main game thread had the core at 30%. I&apos;d expect that at 10-15 hoomans my server would also start lagging and its far more capable than your chip. Your issue is likely more a technical/optimization one rather than a bug.&lt;/p&gt;

                            <comment id="659639" author="uncle fungus" created="Sun, 5 Apr 2020 11:00:18 +0200"  >&lt;p&gt;I&apos;m playing on a fairly standard world with between 5 to 15 other players and it sometimes runs very slowly despite the CPU usage also being low.&lt;/p&gt;

&lt;p&gt;It&apos;s an old Xeon but it is effectively 3 * i7 2700k CPUs, with 32GB of RAM and Windows 10 so it should have no trouble whatsoever running just this one world.&#160; &#160;Server.properties max threads is set to 12.&lt;/p&gt;

&lt;p&gt;I have to keep killing entities, any more than around 300 and the ticks per second becomes noticeably low.&#160; &#160;Ticking area has been scaled back to 4 chunks but it still performs very poorly.&lt;/p&gt;

&lt;p&gt;Like Benjamin, I get better performance on a mundane PC&lt;/p&gt;</comment>

I could have sworn I mentioned it while writing... But it ain&apos;t there, so I added it in now.&lt;/p&gt;</comment>

&lt;p&gt;What OS were you running?&lt;/p&gt;
