HN discussionI am doing this between two UM890 Pros. It was easy to set up and I have had no issues over many months, but I "only" get ~11.6 Gbps between them. This seems to match other reports e.g. https://fangpenlin.com/posts/2024/01/14/high-speed-usb4-mesh...

HN discussionIt is somewhat possible but there's rumors that Intel intentionally nerfs the speed so as not to compete with their datacenter products. It could also just be some other resource limit in the hardware, you usually aren't saturating a thunderbolt connection with just one type of data stream. This guy built a small ring topology network using mini PCs and thunderbolt 4. https://fangpenlin.com/posts/2024/01/14/high-spe…
