Prior to EclipseME, I spent quite a bit of time on jMechanic. Like EclipseME, jMechanic is a plugin for the Eclipse. jMechanic provides the ability to do performance profiling using Sun’s HPROF interface in their JVM.
jMechanic is no longer being developed. At one point, I had hopes that the Eclipse Test & Performance Tools Platform Project would provide a top-notch profiling solution for use in the Eclipse IDE. Unfortunately, while the tools are certainly powerful, they have never really proved to be highly user friendly. These days when I need to do profiling, I tend to use the excellent jProfiler tool.
