Topology - sanity check - eviltoast

Hi all, one of my Eero units (backhauled with ether Ethernet - gigabit connection) is getting slower wifi speeds than the others and this has made me curious if my topology isn’t “optimized” or if it matters.

Currently one of my eero access points is fed Ethernet off of a switch. Should I have it fed from the wall outlet, and then feed the switch off of the second Ethernet port? Does it matter?

For what it’s worth, wired speeds are full ~950 symmetrical, so that works fine.
