Boosting runtime with concurrency controls

Most Power Automate users are familiar with the widely used Apply Each control, which helps with processing lists of items. However, when there's a long list things can get problematic with items being very slow to process, running only one at a time. To overcome this, Satyvir Jasra, writing on the Magnetism Solutions Blog, recommends Concurrency Control. Users can turn the control on through the settings cog and set a maximum of 50 for degree of parallelism.

Much like a regular sequential for loop, Power Automate will display items that failed to run after it processes the entire batch. In a startling contrast, Jasra showed a regular runtime for multiple items which took over four minutes to complete, compared to only 15 seconds with Concurrency Control set to the highest degree of parallelism.
