Jumbo Frame and Link Aggregation on M2 Mac mini and M2 Pro MacBook Pro 16"

[hajime]

Hi, in real use, how is the data transfer speed difference between 1500 and 9000? For example, if it takes 100 seconds to transfer a file at the default 1500, how long will it take to get the same job done with jumbo frame set to 9000?

If I recall correctly, in real world situations, jumbo frames only offer marginally more "throughput"... something like 5% - 10% more. The major downside of jumbo frames is you have to configure all the networking equipment to support them as some equipment might discard the packets.

Thanks.

Is a switch required to set up link aggregation?

I following the steps below to link the stock 1GbE ethernet port of a M2 Mini with a usb-ethernet adapter:

Combine Ethernet ports into a virtual port on Mac

If you have a Mac with more than one Ethernet port, you can combine them into one virtual Ethernet port.

support.apple.com

After setting up, Network shows that the combined virtual port is not connected. Tried to plug the ethernet cable to the stock ethernet port/ethernet adapter. It still shows that it is not connected.

Yep, you also need to configure a Port Aggregation on your Network Switch. Only useful really for Servers or Systems making lots of connections to different targets. It won't bundle 1 connection over both ports.

Network Switch needs to support LACP for Link Aggregation. So looking at Managed Switches.
