I just installed an SFP+ to ethernet adapter to my UniFi Dream machine to feed the lines in my home. I have 6a throughout and I also purchased a 2.5Gb switch for upstairs to feed several devices and I'm really happy. Amazing upgrade for an inexpensive cost.
The original throughput from the Dream Machine was gigabit and a ton of stuff was sharing that line, so the 10Gb SFP+ has addressed that bottleneck. Wifi speed testing is now showing as 20-40% faster than before in the same locations. Ethernet a little bit more than that upstairs. I knew there was a little bit of a bottleneck at times due to the amount of devices, but I honestly didn't imagine/realize that the gigabit was that big of a bottleneck.
I am rebuilding/reinstalling my NAS, so I'm excited to see what improvements to transfer speeds I'll see once that is up and running (reason why I got the SFP+ for the 10Gb). Expecting better than before where the speeds weren't quite fast enough for me to be happy with the performance. That's just me being picky though and not being happy with needing to wait like 5-10 minutes to upload an entire week of vacation photos via wifi and wanting to do it in a fraction of the time.
Also looking forward to reorganizing a few things so I can get a new desk in and have my computer dock set up sorted out without it being as messy as it currently is. A few things being upgraded from USB A to USB C/Thunderbolt (where possible) is also sorting out a lot of annoying laggy bottlenecks I was dealing with before. Also aiming to set up a new area for my IT stuff so that it's more organized and tucked away vs in the way in the utility room.
