It is possible to put a limit on the number of concurrent transfers from a specific data source. Some data sources can only handle a certain number of connections before adding more connections will actually slow down the overall performance of the transfer rather than speed it up. This setting enables you to prevent the execution engine in the Jet Data Manager from doing more concurrent transfers than the source can handle.
To limit the amount of concurrent transfers from a data source, follow the steps below.
In the Business Unit, find the desired source under Data Sources. Right click on the data source and select "Data Source Settings" The Advanced Settings window opens.
In Max Concurrent Transfers, enter the maximum number of concurrent transfers, and click on OK.
