In some commercial virtual machines, Java programs are initially interpreted by the interpreter (interpreter), and when a virtual machine discovers that a method or block of code is running particularly frequently, the code is identified as a " hotspot code ." To improve the efficiency of hot spot code execution, the instant compiler (Just in time Compiler) compi

[Java Performance] JIT compiler IntroductionOverview of JIT compiler using JIT (Just-In-Time) JIT compiler is the core of JVM. It has the greatest impact on program performance. The CPU can only execute assembly code or binary code. All programs must be translated into them before they can be executed by the CPU. C

In many Java applications, you need to invoke the Java compiler in your program to compile and run. However, in earlier versions (Java SE5 and previous versions) only the Java compiler could be invoked through the Com.sun.tools.ja

This article will be the second article in the JVM Performance Tuning series (first: Portal), and the Java compiler will be the focus of this article. In this paper, the author (Eva Andreasson) first introduces different kinds of compilers, and compares the performance of client-side compilation, server-end compiler and multi-layer compilation. Then, at the end
