SharePoint Migration tool general questions

[AlbertSP]

Hi,
I wanted to get a better understanding of the SPMT operations.

If I have the tool installed on Server A in the East coast (200MB/s upload speed) and the ServerB (file to be migrated to SP) on the West coast (50MB/s upload speed), which upload speed is being used?
Is it recommended to install SPMT on the Server B? Otherwise, is the network traffic slows down migration if I keep SPMT on server A?

On a spertated question, the Scan Report shows a root folder with a padlock icon. What does it indicate?

Hi,
The limitation will be in the connection from Server B to Server A. So the recommendation here is either to install SPMT in a machine that is in the same network wherer Server B is or in the Server B as you have mentioned
