Parallel processing in FME is beneficial when there are enough independent groups to process concurrently.

• A. False
• B. True
• C. Not sure
• D. It depends

Answer: (B)

Parallel processing in FME pays off when the workload can be split into several independent tasks that run at the same time. When a workspace has multiple branches or streams that don’t depend on each other, the engine can execute those branches concurrently, making use of multiple CPU cores and speeding up the run. If the workflow is mostly sequential, with steps tightly dependent on the previous results, there’s little opportunity for true parallelism and any overhead from managing threads can outweigh the benefits. So, when there are enough independent groups to process concurrently, parallel processing is beneficial.
