This is why I cut the network to all streaming devices (this means my kids watching something through the NAS) when doing speed tests. The limiting factor is not the vero in my case, but the link through the NAS which is then shared.
Hi Sam - received nothing yet and I was supposed to get a replacement. Have these RMA instructions been sent?
here are my results:

if i use the usb-adapter everything plays well, by using the vero build in ethernet all videos are stuttering and buffering all the time.
Hi Sam,
just got my Vero4K+ yesterday 
so I quickly tried to stream from a new Synology 218+ some 4K 51Mb/s movie, but it started to buffer and stutter after the buffer is empty 
so for the troubleshooting part:
moved from SMB to NFS share
Iperf from Synology to Vero 4K+ : >900Mb/s, and 15-50Mb/s upstream
Ping to Vero 4K from Synology/PC: sometimes timeout… (I can understand ping is low priority but I don’t expect drops on a LAN! … 
Copied the file from Syno to a hard drive on the Laptop at >30MB/s and this file plays fine on the VERO 4K+ from USB.
Checked the NW througput on the synology during streaming= around 9 MB/s, which is strange as both syno & Vero seems to be able to get much more…
which eventually results in froward buffer after buffering: ± 50MB, sloowly going down till it reaches some Kb, and then has to rebuffer again…
=> Why is the Vero4K+ not able to buffer quick enough , while playing the file, though it seems to have still options to get more ? (CPU was also normal, no peaks)
Let me know which next steps I can take , as it’s quite frustrating, I ordered the 4K+ in order to be able to stream those on Gb Nw, and now it fails :(:(:
ps: for the fun, I ran an iperf,during the streaming of the movie, and it still gets around 800-900 Mb/s … and stutters… is it a priority thing that Kodi needs to get more CPU to stream quicker?
tx Sam!

Hi Basti,
let me try some USB adapter as well…
tx
Do you have any other devices in between?
I have a Vero 4K+ here and over 900Mbps in both directions.
It however requires decent equipment. What Switch do you use? Could it be the switch is the limiting factor here?
Hi Smurphy,
though I’ve got 2 switches, I will steal the uplink and try again.
Switch is a decent Procurve Gb switch
Now … as indicated by Basti, I just tried a USB-Ethernet adapter… and no buffering it seems … (didn’t watch a full movie yet though
so this really sounds like an issue to allocate the resources on the built-in Ethernet, which is capable of Gb, but seems to have issues somehow ?
Edit: or re-reading above posts, the lower Iperf on the traffic backwards might explain the lack of receiving ACK’s on time, and lower the overall throughput (probably something Iperf isn’t testing with basic parameters?) and also this could explain why I lose ping packets (even if the unit is not doing anything), which I think is really awkward
edit2:
quite low indeed

Your replacement was shipped on Tuesday, so you should get it tomorrow
OK, thanks!
Possibly — can you test it in another environment?

so I’m quite confused
could it be something related to warmth ? (after being used some time)?
kind of lost atm
Edit1:
I must note that there were no profiles logged in atm of those tests, compared to the other tests .
I just logged in Kodi profile, and lost some pings again, which doesn’t seem the case when not logged in…
Keeping an eye & doing more tests
Edit2: Now it becomes interesting:
Played a piece of the movie, it sustained, but at the limit.
Trying iperf leads to a much lower result during playback (which could be logical, still on USB it gets more output), and then I stopped the movie, logged of the user from Kodi to be sure no remaining traffic(which I can also see frmo synology ) running iperf now gives only:

RMA ?
tx Sam
@sam_nazarko: I think I recall you saying somewhere that you’ve made some changes to the 4K+ Ethernet driver which prioritise receiving data over transmitting it. Did you actually say that, or did I just imagine it?
@chfauc2 Your test setup with a direct LAN cable between Vero4k+ and PC I find very interesting!
If you want and you have a normal and a crossover LAN cable could you repeat the iperf3 tests (iperf3 server running on PC) with cases
- Vero4k+ sending to PC, normal LAN cable
- Vero4k+ receiving from PC, normal LAN cable
- Vero4k+ sending to PC, crossover LAN cable
- Vero4k+ receiving from PC, crossover LAN cable
In this scenarios all active network components are eliminated and in case the “issue” of unidirectional unstable and small bandwidth moves with the cable, it could indicate a HW issue bound to specific twisted pairs of the LAN cable.
Thx in advance if you want to invest time in this and never mind if you lost interest.
Mention @sam_nazarko explicitely this way in your response regarding RMA process.
Hi Jim will check when I’ve some time…
though, I would need to also watch a movie from the Ethernet port at that time, and test at several times. (more tricky to organize)
As you can see from my last post, all was good on the switch (to my surprise), but after 10 mins movie watching, the iperf went low again, and got better per minute (of cooldown of not doing anything ?)
can someone with issues else do that test as well?
Edit1:
Note that I used a brand new cable for this test, and swapped to other cables to in the past tests ,to prevent cable issues

That’s correct
That is caused by clock drift and is something I fixed in May this year. Can you get the temperature from System Info when the connection performance is good and when it’s poor?
Thanks
Sam
Maybe it is not very important but i thought i should share it with you anyway. After reading all these posts i decided to test my Vero4k+. I installed iperf3 and did the recommended test. Result: Wired with Gigabit i only got round about 190MBit/s. Using udp instead of tcp packets gave me 940MBit/s. My standard setup uses 2 TP-LINK Gigabit Switches, so i hooked up my vero directly to my PC. I got 940 MBit with both, tcp and udp packets. I hooked up one switch and after testing the second, always got 940 Mbit. So i restored my normal setup and now i get 940 MBit/s every time i test it. What i want to say with that, if you have Network Problems, first reboot EVERYTHING, even your switches .-)
@sam_nazarko, again i can only thank you for support here. Thats why i bought a Vero 4k and after i got the announcement mail directly a Vero 4k+. Please keep up the good work and i will buy the next Generation of the Vero Device too

iperf Done.
will edit post in 5 more mins
That doesn’t look like a big change to me. The device can run up to 118C without issues.
If the device gets warmer, does the TX performance completely die?
Sam
might be on a working device :-p
… still NW throughput increase/decreases by the minute the temperature changes, even by small nrs…
(and USB -ethernet doesn’t seem to have this impact)
further ideas what’ I can do next?
Edit1:
Following [s_muentefer]'s idea, rebooted the Vero, so same last temperature, same low throughput. so no change after reboot
Then:
Halted system for cooldown (10 mins)
=> back at normal speed, see below
