jitwatch
A log analyzer and visualizer for the Java HotSpot JIT compiler, enabling inspection of inlining, hot methods, bytecode, and assembly.
What is jitwatch?
JITWatch is a log analyzer and visualizer for the Java HotSpot JIT compiler. It parses compiler logs to show inlining decisions, hot methods, bytecode, and generated assembly, helping developers understand runtime optimizations. The tool provides a JavaFX-based interface for interactive exploration of compilation behavior.
Java developers, performance engineers, and JVM researchers who need to analyze and optimize JIT compilation behavior in their applications.
Developers choose JITWatch for its specialized focus on JIT compiler introspection, offering a unique visual interface to debug performance issues and understand optimization decisions that are otherwise opaque in standard profiling tools.
