This is incredibly useful when debugging workflows that take a lot of time and is similar to the performance recorder in Tableau which allows you to identify which query or workflow is taking a lot of time
We’re glad to see this option getting some attention. It’s a great way to see which parts of the workflow might be suitable for optimization.
One other pro-tip worth mentioning: Performance Profiling is intended for use during development and debugging, as it may cause a very slight decrease the overall performance of the workflow, especially with larger workflows and/or with some older operating systems and hardware. This is why the option is unchecked by default.
Once a workflow is ready to move into production, simply uncheck the option and you’re good to go.
