Just got my new Apple TV yesterday and set it up. Network performance (wired) has been extremely slow. Many apps like movies, Netflix, Hulu show blank icons and going to watch or preview something takes a really long time. My previous (slower) Apple tv played everything instantly and had no problems loading content. Anyone else experiencing this? I’ve already rebooted it.
 
Nope. No issues. Also wired. You didn't say what your prior ATV was? Both 4k models have gigabit ethernet. I believe all the prior ones have 100Mb ethernet. Possibly the new ATV is having issues negotiating a gigabit connection with your switch? I'd try changing ports on the switch end. Hmm. Then you get into the length of copper in between and what calibre of cable was used.

If you switch to wireless do the performance issues go away?

The previous one was the 1st gen 4K. I’m on a gigabit internet connection.
 
Yeah, I wasn't asking about your internet connection (yet) :). Good to know it's quick. Sounds like the issue may be local. Like I asked - have you tried switching to wireless?
I will try that although it's baffling all I did was switch apple tv's. Maybe I should just reboot my modem and router.

It certainly wouldn't hurt rebooting your modem / router. You can also re-seat the ethernet cable in the jack in the ATV as well (maybe it's not completely clicked in?) If you can, also look at the copper pins on the cable - make sure none of them look dirty. :) Flipping to wireless would have isolated the problem to your wired connection. (if flipping to wireless didn't resolve the issue, then the problem could be elsewhere) - such as some element that migrated from your ATV4kv1 to your v2 which is incompatible or corrupt in the configuration (setting up your new ATV4kv2 as a new device / not migrating any information over and doing some testing could isolate if that's the case).

Well, I rebooted my modem and router and it didn‘t solve it. I also re-seated the Ethernet cable. When I set up the new box, I did the thing where I brought my iPhone close to it and set it up that way. It synced all the apps i have on my Apple TV’s.

Well, I'd do the wireless test before blowing it away (as that will take some time).
If changing to wireless eliminates the issue, then the issue is isolated to Ethernet (and, in all likelihood, the ATV is using the same chipset for Wireless and Wired networking). In that case, I'd try a known-good cable, directly plug the ATV into your router (eliminating all of the cabling in between). If the performance problem goes away, then you have a problem in your cabling between.

If that didn't fix the issue, and you want to try eliminating your configuration from the equation, you do a factory reset of your ATV - (you go into Settings, System, Reset)
I'd also select Reset and Update if possible. (did your ATV do a TVOS update as part of the initial setup?)
- then set the ATV up as a new device - do NOT use your iPhone to migrate your data, do not enable one screen - I'd also use a different Apple ID just to make sure (create a new one if you need to). This eliminates the potential for your settings being the culprit.

(You could at this point - or anytime before decide to contact Apple support) :) They're likely to take you through similar steps though.

If setting up the ATV as a new device with a different Apple ID doesn't resolve the problem, then there's only two real potential problems left. You have corrupt TVOS (there should be instructions out there to get the ATV4k into DFU mode to be able to blast a fresh, downloaded TVOS onto it from your Mac or Windows box) or you have defective hardware in your ATV4k.
 
What numbers do you see when you run the Speedtest app on your ATV?
Pretty pitiful. I hadn’t thought of that so I ran it and I get 21Mbps down 29.7Mbps up. 21ms ping.

I just ran it on my iPad Pro and got 566Mbps down and 23Mbps up.
 
Well, looks like I solved it. I had plugged my new Apple TV into the same power cable as my 1st gen Apple TV 4K. I went and got the new cable and connected it and now my download is 942Mbps

Good news. I do not know how a power cord could cause a communications drop, but anything is possible.

Yeah, maybe the wiring is a little different and it wasn’t giving enough power to the networking controller. I guess I just learned to always use the power cable that comes with a device.

interesting. I left my old one in too. I’ll try to replace it and see if there’s any difference.

I am also using old AppleTV 4K power cable. Too lazy to switch to 2021 AppleTV 4K cable. New ATV is much zippier accessing (cat6 network) content from my MacMini video server. The A12 powered ATV is worth the upgrade for me. Content/pages load 2x faster. Previous 4K wasn't really laggy but I'm loving the new set top box's improved performance. I ran the Speed Test app and still getting similar 942/743 down/up speeds as my previous ATV.

On another note I noticed that top INFO SCREEN no longer displays 4K when playing video. It displays HD for everything. Was this something removed in TVOS 14.5 as I haven't checked since upgrading? I'm running Dolby Vision 4K 60Hz and should be receiving an 8K capable HDMI 2.1 cable today. Not sure what to expect as I'm not sure about class of current cable?

I noticed the same thing (HD in the drop down). Tv (LG C9) says it’s in DV Cinema, tho.
 
Well, I guess that didn’t quote fix it. I’m still seeing content icons load really slow, or not at all.

Although a bit OT, I made an observation on my brand new ATV4K (2021):

When it is in sleep mode, the LAN port shifts down to 100 MBit/s after some time. Roughly every 5 minutes, it raises to 1 Gbit/s for mostly 1 minute and downshifts to 100 MBit/s again. Then it starts all over. I can observe this in my router dashboard (all LAN ports set to 1 GBit/s). When it is in normal operation mode, it seems to stay at 1 Gbit/s.

Did You notice that, too? Maybe that is a kind of power saving strategy?

That may kind of explain why I was having extremely slow internet speeds with my 1st gen power cable connected and then when I connected the new cable to this box the speed shot right up to gig.

I'm still not sure why I'm having slow loading, missing icons, content not loading at all though. Wondering if I need to completely reset it and set up again.

Don't think so. This was more or less coincidental because the two power cords are exactly the same.

I have the same problem. It switches very slowly between apps and some screens. it seems to turn off transiently. once the app is open everything streams perfectly fine.

I am glad I found this post because I was considering buying the ATV 4K (2021) model, but I have the 1st Gen model and it is doing the exact same thing you mentioned regarding downshifting to 100Mbps when in sleep mode. I have a Cisco gigabit switch and I'm able to look at the logs to see the interface bouncing and eventually shuts downs for hours. The problem I'm having now is when the device is powered back up for using, it only auto negotiates to 100Mbps. It is not a cabling issue or switch port issue because I've tried multiple cables and even a different switch. I have two of the HD models and neither experience this issue. Both interfaces on the HD models never shutdown.
