Outdated knowledge.<p>PHP with its shared nothing design makes it very scalable, the 2016 implementations are very fast and consume little memory. LuaJIT see other post. Object-C (there is C underneath, read <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Object-C" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Object-C</a> ). Check out Julia, it&#x27;s great. You can write pretty low level code in modern languages like Go, Rust without loosing everything (don&#x27;t come with Sing# and Java related misc things, yada yada). Also my point was that these languages consume less memory. I have yet to see a Java or dotNet application that doesn&#x27;t consume too much memory for my feeling (not to mention the GC idioms). When I read that people put monolithic Java enterprise apps in Docker containers or wonder why the new Startmenu crashes that often, it reminds me why I care about computer resources. After all we are still stuck with 3.8GHz single core performance, same as 2004! (memory bandwith,etc got faster, I know) Give me a 10 GHz single core CPU and we can start talking.
