I guess I'm a little confused about this whole question/issue.
In network terms, "bridging" is when you connect two networks together as part of the same network, without interposing a router between them; the "bridged networks" are topologically part of a single network...
What a switch does is bridging (as opposed to routing).
In the old days, bridging was commonly used by cable modems.....
Your network, and those of your closest neighbors, were all connected to the same "network node", and your cable modem acted as a "bridge"... connecting your network to "the" network.
From the point of view of the main network, you and your neighbors were simply connected to one subnet.
And, yes, bridging is usually faster, and with lower latency, than routing.
However, once you reach that point, there are other considerations.
For example, a cut-through switch will have lower latency than a store-and-forward type switch (but is more likely to create occasional bad packets).
And all of this is so far "above" anything that matters for computer audio that it isn't even funny.
I read that article on Computer Audiophile:
It's interesting, but I seem to perceive a bit of a gap in understanding about how networks "work".
(He seems to find things "interesting" that are really just "how networks work"... like having a sigle DHCP server service two networks which are bridged together into a single network.)
For example, the author expended significant effort in figuring out how to "bridge" the two Ethernet ports on his Mac Mini (all this means is that he configured them to be on the same subnet).
It would have been much easier to connect one of those ports to an external Ethernet SWITCH.
All of the ports on a switch are "bridged together", so they're all part of the same network, and the circuitry on most switches is crazy fast compared to the Ethernet circuitry inside a Mac.
Bridging the two ports on the Mac might provide a slightly faster network connection between the Mac and the network... but the Mac Mini isn't fast enough itself for that to be likely to matter.
And, to provide the fastest possible connections between other devices on the network, an external cut-through switch will be far and away the fastest - with the lowest latency.
(Most small Ethernet switches don't even mention whether they are store-and-forward or cut-through... because both are so fast that it's considered to be largely irrelevant.)
