+My Java application has performance issues - help me set up comprehensive profiling process using @151-java-profiling-detect.mdc and use the location examples/spring-boot-memory-leak-demo/profiler
+
+Analyze the results located in examples/spring-boot-memory-leak-demo/profiler and use the cursor rule @152-java-profiling-analyze
+
+Review if the problems was solved with last refactoring using the reports located in @/results with the cursor rule 154-java-profiling-compare.mdc
