How can I find the cause of my DSL saturation

I'm a retired computer scientist who has his own network.  I was caught with my pants down when in 2023May my Exchange 2013 server became undesirable by others because of it's limit TLS capability.  I was forced to upgrade my network.

I bought a more powerful box (hardware) and upgraded to Server 2019 and Exchange 2019.  Everything was fine until I brought the new Exchange Server online.  My DSL line became over-saturated, apparently by a huge number of send packets.  Being a single individual, my network has little traffic.  My highest usage is probably from watching NetFlix (hey, I'm retired).  I get little email, thanks to using Proofpoint Essentials to screen the SPAM away from my server.  I send just a few emails a day.  So I'm surprised that cutting over to the new Exchange Server saturated my network.

How can I track down what is causing my network saturation?
