A little strange but they stuck with it for &lt;i&gt;6 years&lt;/i&gt; until suddenly this summer they announce Windows 11 and they went &lt;i&gt;hard&lt;/i&gt; talking up how it was a huge change to Windows but in reality it isn&amp;#x27;t. At all.&lt;p&gt;It has a new visual layer sure but the applications are still the old Windows 10 (and so really the old Windows XP?) ones with that new look. They introduced a new store and support for additional stores such as the Amazon Android app store.&lt;p&gt;I guess what I am saying is I don&amp;#x27;t get &lt;i&gt;why now&lt;/i&gt; they are calling it Windows 11? They could have just carried on calling it Windows 10. They have introduced big UI and feature changes in previous Windows 10 updates (perhaps not quite as big as the new taskbar and Explorer changes).&lt;p&gt;It is a free upgrade for Windows 10 license holders (consumer anyway, not sure how it works for Enterprise?).&lt;p&gt;It just all feels so rushed and messy and the end product is just not very good as we can clearly see here.&lt;p&gt;I don&amp;#x27;t want to hate on Windows, after all they have introduced some really interesting new things since Windows 10 initial release such as WSL. It is just there didn&amp;#x27;t appear to be a want or need for a Windows 11 and this rushed mess makes it look like Microsoft didn&amp;#x27;t (doesn&amp;#x27;t?) know what it is doing with Windows either. Shrug.</text></comment>

Is it that Windows 11 is constantly running code and&amp;#x2F;or using data so that it consumes more of the L3 cache all the time? But only on AMD? Is this really a linear slowdown of cache speed as the article&amp;#x27;s wording implies, or is it some more complicated slowdown that they&amp;#x27;ve benchmarked with something that intrinsically measures it linearly?&lt;p&gt;Problems with the thread migration to certain classes of CPUs I can kind of understand, that&amp;#x27;s still fairly new code for windows, but how it can slow down the L3 cache in the described way is a bit of a mystery to me.</text></comment>
