Understanding where Scala generates boxing, closures, and virtual dispatch tells you which patterns are safe in hot paths and which aren't. https://blog.turboawesome.win/2013/07/jvm-jit-compilation-what-the-c2-compiler-does-to-your-loops/ Tue, 30 Jul 2013 14:11:00 +0000 https://blog.turboawesome.win/2013/07/jvm-jit-compilation-what-the-c2-compiler-does-to-your-loops/ The HotSpot C2 compiler can transform your Java bytecode into surprisingly efficient native code — but only under specific conditions. Understanding those conditions explains a class of mysterious performance cliffs.
