I have tried testing this and I believe the test you are performing is between the PC you are typing the address into and the ATV itself...not the server and the ATV. I tried this test from my laptop via WIFI and Ethernet to find this out as I was only getting 600ish mbps via Wifi vs 940ish mbps via Ethernet.

I wish they added the speedtest function in the app.

Good stuff though.

Well I'll be damned: It is. That's kind of... not as useful as it could be. Time for an enhancement request, I guess. I had just assumed it was doing the same speed test as Android and Fire TV devices.

@scooter_scott: What did you use for running that speed test: A wired device, such as a computer, or a device on WiFi?

Wired mac mini --> Netgear ProSafe switch --> Netgear ProSafe switch --> wired ATV4

So you have 2 switches? What are the connection speeds to each port?

I go wired LAPTOP-->Netgear Pro GS308T-->Asus ac88u-->wired ATV and I get 940ish mbps. Something in that path has a 100mbps link.

The ATV4 has a 100Mb link. All switches are gigabit ports.

Ok, well, then, assuming your LAN isn't slammed with traffic and those NetGear ProSafe switches are GigE switches: Something ain't right. You should be seeing at least 80% of rated max bandwidth, not 10%.

Why does the ATV4 have only a 100mb/s link?

Oh that's right, the ATV4 non-4k is a 10/100 port.

Still shouldn't be an issue. My Sony TV only has a 10/100 port as well.

Because Apple didn't put a gig port on it

Oh... ATV v4, not ATV 4K. My bad.

Have you checked you Pro switch port monitors to look for packet errors?

Did you check you NAS for packet errors as well as @jseymour recommended?

I don't know if I have those...they are unmanaged switches

Are they all ATV v4 (non 4k)?
Are all of your ATV's wired?
Have you tried using wifi (should go faster than 100 Mbit/s)?

Could it be your ATV updated to tvOS 13.4 at the same time you moved servers?

Sorry I assumed they were managed. You can check out for port errors on your NAS at least. I have a QNAP so I can't help you but I would imagine that there is a system info app or similar that monitors your NAS hardware to give that info.

2 of them are wired. 1 ATV4, 1ATV4k, 1 Wifi ATV4. I'll check the TVos version on them.
Correct WiFi is faster...but according to what I've seen @tmm1 post in the past you don't need that much bandwidth for Channels and the 100Mb port is fully capable.

Looks like mine has pretty solid as well. I really don't think its the NAS.

Correct. 100mb/s is more than enough. But I'd try it on WiFi just for the test.

Yup. Looks good.

I'm out of ideas, for now. Maybe try different ports on your switches? A different ATV on the same port(s)?

It would be nice if these IoT devices, such as the ATV, had a page that would report network stats, like that ifconfig output.

Is there anyway you can bypass one switch at a time to test? It could be one of the switches or a cable.

This happens on all the ATVs? Which switch is the router for wifi plugged into?

Yes the ATV4 is on 13.4.

Not saying this is the issue, but you may want to look at this thread regarding dropped frames and low on cache which both appear in your first few postings.

I looked at his logs and I see some similarity but I also see where his is having an issue connecting to his DVR. I don’t see a lost connection to my DVR.

Since switching my audio setting on the ATV4 settings my video/audio has been pretty stable
