Eventually I may have time to also x-check with my 2018 15” MBP and also Android Domo smartphone. However, that said….Non sequitur: Excess latency/jitter may well not display on your Hub Flow tests- as you have not defined any(nor comprehensive) test parameters? ….YET, and this only occurs on VM Connect app so if you wish to provide an evidential comparison with any degree of credibility you will need to provide a lot more detail comparative to my OP at top of this thread.Otherwise whilst I’m grateful for your response I don’t want to mislead you into wasting MY TIME as demonstrated by some of your colleagues in my other thread! 😉

Complexity and simplicity are relative terms that depend on the context and purpose of a matter. While simplifying things can make them easier to understand and manage, sometimes complications are necessary to accurately capture the nuances of a situation or to address specific needs and requirements.There is no universal answer as to whether it is better to complicate or simplify matters. It ultimately depends on the specific situation and what the goals are. In some cases, simplifying matters can lead to a loss of important information or details, while in others, complicating things can add unnecessary layers of complexity and confusion.Ultimately, the key is to strike a balance between complexity and simplicity that meets the needs of the situation at hand, while still being effective and efficient.

Brilliant! The here is a draft reply from the FT:Hey Buffer 6,Sorry to learn that complexity and simplicity are affecting your broadband experience with us.We’ve looked into you account and everything appears to be within required limits. Have you tried a pinhole reset of your Hub? This is unnecessarily complex which will suit you perfectly. The simple bit is finding a paper clip the end of which needs to be stuck into the pinhole reset hole for 60 seconds. This action will destroy all your settings and thus ensure that your Hub is in a perfect state for you to enjoy.Yah OK.Horsey can translate your brilliant note into Latin. It needs that!

There is a coding error in the application, which, of course begs the question, what other 'issues' might there be with it? I'm reminded of the web interface on the Hub 4 which insists as reporting S/N ratios to five places of decimal plus quite a few of the channels would report an identical value to the same five decimal places - which is obviously rubbish. So again we have to question the reliably of what we are given, now I suppose from VM's perspective, the vast, vast majority of users never, ever look at the hub stats so it probably isn't seen as a big issue... and note that the VM bod hasn't addressed the Connect App issue. They can surely do better than that? No, Seph, they really can't😉Well not if they want to keep their job, as openly admitting that a VM product is not 100% perfect and certainly not flawed in any way, would be something of a 'career limiting' move, no?Kei won't be happy with them.......

VM Connect App on IOS has recorded excessive Hub3 latency

what we don't know is if it upstream or downstream with that latency test I'm guessing downstream
Why yes their would be excessive latency given how the test works it floods the downstream with the hub rate limiting and buffer your connection.

It why VM should not be doing auto speed tests on hub in router mode.

  Whilst seeking to keep an open mind and thus still appreciating any post unaccompanied by any evidential data the use of “we” and “guessed” does’nt add any credibility……. IMHO….
  Since “my” continued results of latency exceeds 10s (and jitter >200ms) are “apparently” using “SamKnows” servers for Hub3 yet also WiFi but unsupported (yet) by any other non VM. Connect diagnostic then obvious “comment/query” will also include:
  1. Is this a SK ISSUE?
  2. Or a VM “overlay” on specific Hub?
  3. Does a v11 Hub3/different NMS soft/firmware/or Hub4-5 experience similar Excess latency/jitter?
  Upgrade to IOS 16.3 still results in same excess….. AND ….
  AFTER 7 ELAPSED,5 WORKING DAYS READERS WILL NOTE THAT VM FT HAVE NOT YET REPLIED!
  Enquiring minds would still appreciate the courtesy of official VM acknowledgement of symptom even if potential answer or escalation exceeds FT diagnostic expertise and/or authorisation!

    Thanks for your post on our Community Forums horseman and welcome back to our Forums.
    
    Sorry to hear of the latency issues that have been flagged on the Connect Application.
    
    Can you please confirm if you experience latency on just this one device or multiple?
    
    Having ran a flow on your hub, no issues appeared to be present.
    
    Kindest regards,

OK I have read this entire thread and I cannot make heads or tails of anything.
1) The VM connect app is certainly broken. But does it need to be fixed? Not in my opinion. I'd rather VM completely forget about this app and focus their money and attention on their network infrastructure, not some pointless app.
2) Latency is typically measured using ICMP packets, this is a completely different protocol to usual protocols such as TCP/UDP/SIP. ICMP will typically be given the lowest priority by networking hardware including the hub, which is why you are seeing ridiculously high latency.
3) If you need to measure latency, use the ping command and ping bbc.co.uk or google.co.uk, or other important peer IP. Measuring latency to your local speedtest server using a proprietary mobile phone app is pointless. You need to measure your latency to an actual endpoint which you are communicating with using a proper ping utility, definitely not using an iPad app lol.

  "If you need to measure latency, use the ping command and ping bbc.co.uk or google.co.uk," where will that get you? Ping uses ICMP.

    It'll get you past the dodgy VM Hubs. The issue is not ICMP. The issue here, in my opinion, is how the Hubs handle ICMP when the Hub itself is either the source or destination of the probe.
    When you use a separate LAN device, that LAN device becomes the source as far as the Hub is concerned. The ICMP packet is simply another packet it needs to forward; it won’t respond itself. I have not experienced any issues when the VM HUB is simply routing/forwarding ICMP packets and is not the source/destination of the ICMP probe.
    This can be tested using the Hub3's built in ping utility. Try to ping a local IP, every now and then you will get some ridiculous figure like "14323ms", this is not a network issue, it's because the hub's firmware...
    You can also try pinging the Hub itself, locally. All Ethernet devices on my network are less than 1ms, most are around 0.4ms. But the Hub3 hovers around 3ms.

Nothing wrong with ICMP. Indeed, Tracert tells you exactly which node(s) is/are busy with priority traffic - which is a clue as to what's going on.
But yes, the CONNECT app is useless and do let Horsey have his fun with VM.
