Performance bottlenecks
How to find a performance bottleneck using CPU profiling?
Let us assume there is a task in your application that you want to profile. Please do the following:
- Run application with the profiler
- Connect to the application
- Start CPU profiling right before the task is started
- Wait until the task finishes or performs long enough
- Capture performance snapshot
- Open the snapshot and use CPU view
