19. Concurent connections to multiple devices

When you need to connect to a large number of devices, it will take quite a long time to complete the connections one by one. Of course, it will be faster than manual connection, but it would be faster to connect to equipment in parallel.

Module concurrent.futures is used for parallel connection to devices in this section.

Note

All these “long” and “faster” are relative concepts, but in this section we will learn to measure exact script execution time to compare how quick the connection is established.
