Hi Joe, Actually, I've been seeing exactly the same problem too, if I to dynamically attach to the running JRuby (which is a most simplest way to profile the running app with no modifications how the app starts).
Oh well, so I reverted to the good old/proper way to start profiling app with additional command line parameters, and then it worked just fine :) So, here's what I do: 1. I copied jruby.bat to jruby-profile.bat 2. Added the following after %_VM_OPTS% but before -cp there: -agentpath:D:\re\NetBeans-6.0-RC1\profiler2\lib\deployed\jdk16\windows\profilerinterface.dll=D:\re\NetBeans-6.0-RC1\profiler2\lib,5140 (when you follow your profiler wizard you'll be provided with proper line for your environment) 3. In Netbeans "Attach Wizard", select Attach Method: Local. Attach Invocation: "Direct". 4. For CPU profiling, create a new custom profile, I called it JRuby. This can be done from "Attach Profiler" screen (there is a link on the left: "Create Custom...") 5. In settings: "Entire Application". Filter: "Quck Filter". I typically select org.jruby.* as inclusion pattern to instrument classes. 6. Start jruby-profile.bat. It will start, and will wait for connection, not running anything, which is good: you could start proifiling from the very start. And that's it. Things to be aware of: Running under debugger is much slower (expected). It's much more useful to analyze snapshots rather than Live Results (more info available for snapshots, like "Hot Spots" and "Combined". Combined tab is the most useful one.
