Welcome to Microsoft Q&A, thank you for posting your here!!
The time taken to download the data to on-premises depends on your local network bandwidth.
- Do you want to transfer large datasets over network, and you have a moderate to high network bandwidth?
If yes, see: Scenario 2: Transfer large datasets with moderate to high network bandwidth.
Moderate network bandwidth (100 Mbps - 1 Gbps)
With moderate network bandwidth, you need to project the time for data transfer over the network.
Use the following table to estimate the time and based on that, choose between an offline transfer or over the network transfer. The table shows the projected time for network data transfer, for various available network bandwidths (assuming 90% utilization).
