JIT vs AOT Compilation

jg21 writes "This article on "Penguin-Driven" JVMs takes a look the performance of Java GUI applications based on the JFC/Swing API, and contends that the JIT-powered JVMs can't match a JVM with an ahead-of-time compiler ported to the Linux/x86 platform. With AOT compilation, says the CTO who has written this piece, real-world Swing applications performed perceivably faster. One is left wondering, will we now see the 'microbenchmark war' carried into the Linux camp?"
