What is the method for debugging performance in Groovy in Java?

The methods for debugging Groovy performance in Java are similar to debugging Java performance, here are some commonly used methods:

1. Utilize performance analysis tools such as VisualVM and JProfiler to measure the performance of Groovy code.
2. Utilize logging: Insert logging in the code to record crucial execution time points and the values of key variables for future analysis.
3. Use time measurement tools: You can utilize methods like System.currentTimeMillis() or System.nanoTime() to measure the execution time of code blocks, in order to identify where performance bottlenecks may be located.
4. Utilize code review tools: Use code review tools to analyze the quality and performance of Groovy code, and provide recommendations for improvement.
5. Performance testing framework can be used to conduct stress testing and evaluate the performance of Groovy code.

By using the above methods, we can have a more comprehensive understanding of performance bottlenecks in Groovy code, identify areas for optimization, and make corresponding improvements.
