| A private flow has its own strategy for exception HANDLING. It also does not have a source defined. | 1. ALTHOUGH a sublow processes messages synchronously, it GETS the strategy of processing and of exception handling from the calling flow. |
| Flows can have sources (such as HTTP Listener to RECEIVE a request) that trigger the flow execution. | 2. Subflows don’t have event sources. For example, you can’t PLACE an HTTP Listener in subflow. |
| Referring flows gives a performance not as good as compared to subflows. | 3. Referring subflows gives better performance |
| Each flow can have its own error handling. | 4. Subflows don’t have an error handling. It inherits the error handling strategy from parent flow. |
