+#### `ForEach` vs `ForEachItem`
+
+Both `ForEach` and `ForEachItem` are similar, but there are specific use cases that suit one over the other:
+- `ForEach` generates a lot of [Task Runs](./02.taskruns.md) which can impact performance.
+- `ForEachItem` generates separate executions using [Subflows](../10.subflows.md) for the group of tasks. This scales better for larger datasets.
+
+Read more about performance optimization [here](../../14.best-practices/0.flows.md#task-in-the-same-execution).
