Rider Profiling Instructions for Windows (.NET process)

NB! This article covers only .NET Rider process (JetBrains.ReSharper.Host) on Windows. For Java process (JetBrains Rider) related issues refer to this article.

Embedded profiler

  1. Start Rider;
  2. Call Tools | Backend Profiling | Start Timeline, Start Sampling or Dump Memory;
  3. Wait until you see "Profiling in progress: stop it manually" message at the bottom; 
  4. Perform actions which are slow in Rider (typing, switching between documents, building, etc.);
  5. To stop profiling, call Tools | Backend: Stop Profiling;
  6. At the right bottom corner, you will get a popup with a performance snapshot file name and "Show in Explorer" link to open a folder;
  7. Share the file with us, some ways are mentioned here
  8. Create a new issue in Rider issue tracker. In the issue, provide a short description of the performance problems you're experiencing, and specify the name of your snapshot.

 

Standalone JetBrains dotTrace profiler

  1. Download and install JetBrains dotTrace profiler:
  2. Start dotTrace and select Profile Local App | .NET Process.
  3. Make sure the following options are set in Profiler Options:
    • Profiling type: Timeline (or Sampling, or Tracing if you has been asked to collect a Sampling or a Tracing snapshot respectively)
    • Start immediately: on (if you're experiencing performance problems on Rider startup or during solution loading) or off otherwise
  4. Click Run
  5. Run Rider
  6. If there's a performance problem during startup:
    • Wait while Rider starts, open your solution;
    • Wait until the solution is loaded and Rider finishes loading caches;
    • Click Get Snapshot'n'Wait button in the profiling controller window;
  7. Otherwise:
    • Wait while Rider starts, open your solution
    • Click Start button in the profiling controller window
    • Perform actions which are slow in Rider (typing, switching between documents, building, etc.)
    • Click Get Snapshot'n'Wait button in the profiling controller window
  8. If you would like to create a new snapshot without saving the current one, click Drop in the profiling controller window
  9. In dotTrace Performance Viewer, save the resulting snapshot using the File | Export Snapshot... menu
  10. Compress the snapshot file using Zip
  11. Share the file with us, some ways are mentioned here 
  12. Create a new issue in Rider issue tracker. In the issue, provide a short description of the performance problems you're experiencing, and specify the name of your snapshot.

I'm having problems with the Embedded Profiler after Step #2 - i.e. nothing happens when I click Start Sampling or Start Timeline, there is no message at the bottom of the IDE. Another colleague has the same problem. Thanks.
