Orbi960 and GS110MEX speed slow when using 2.5Gb Ethernets
When I connect my Orbi to my Netgear switch via 2.5Gb ports, the transfer speed from a wired Mac is about half when I use a 1Gb port between the two. My setup is simple for testing purposes, and I have no other devices and using a Cat8 cable between the Orbi and the Switch.
I run a speedtest from my Mac which is 1Gb wired, and when it transverses over the 2.5Gb connection, I only get ~350Mb but when I move the cable from the Orbi (still using the 2.5Gb port) to a 1Gb port on the switch, the speedtest increases to ~1Gb. I have verified the 2.5Gb connection is actually 2.5Gb and Full-Duplex using the Switch console. This is very perplexing and when I originally installed them last June, I don't recall having this issue and both the Switch and Router are at current firmwares. I have tried a Cat6 cable as well with the same results.
Any thoughts on why I would see such a drop in transfer speeds using 2.5Gb to 2.5Gb versus the 2.5Gb to 1Gb port connections?

Might try a different switch.
Does Mac directly connected to the 2.5Gb LAN port in back of the RBR show a expected 1Gb speed to your PC?
I don't have another switch easily available, and I did connect the Mac 1Gb into the Orbi and got the expected 1Gb speed.
I did some quick tests from my Mac all when the Orbi and the Switch are connected via 1Gb ports. My Mac into the Switches 2.5Gb port (running at 1Gb) and I get the 1Gb transfer rate, My Mac into the Orbi 2.5Gb port and I get the 1Gb transfer rate. I also for giggles plugged the Orbi and Switch to each other via 2.5gb ports and speed tanked to ~350Mbps.
You'll need to test out another switch, if your getting to spec speeds directly to the back of the RBR with your PC and then the switching in the middle at the 2.5Gb port tanks the speed, points to this switch being the issue.
