Help understand my graph


[link to this post]
 
My Graph

I'm new to using the broadband quality monitor thing so not sure what the various parts of graph represent in terms of good/bad.

I gather the yellow peaks I shouldn't worry about because it's probably just be the router prioritising other traffic over the pings, is that correct?

There seems to be a solid, not insignificant chunk of yellow above holding at 40ms latency. That seems rather high to me, or is that again nothing to be concerned about?

Would you consider an average of 20ms latency reasonable on what should be a 100mbps cable connection?

SuperHub 3? This generally has more jitter which is what the yellow is showing but the superhub is often poor at responding which makes the jitter look worse.

Baseline 20ms is normal for cable, largely down to what looks like some congestion on the virgin side of LINX networks to the outside world.

If you are a gamer you would probably be able to tell the difference between this and nominally slower VDSL2 service i.e. actual game play is often better on VDSL2 but downloading patches can be faster on Virgin Media

Yes hub 3, that's how I ended up here. Trying to resolve issues between my hub3 (that was sent to replace an older hub that finally gave up) and my router.

Trying to figure out what's causing the issue(s).

Time to start a thread in the VM forum here about whatever issue it is you have? It would probably not be noticed if you told us about it in this one smile, but that forum is fairly active over the last three months at least.

A Search there over a longish period (see the top menu) might even find it discussed, before you post yourself.

Short is the Intel Puma bugs are not helping, there are firmware upgrades, but some thoughts are that this is masking the issue rather than actually fixing things.

Generally if a server is inside the Virgin Media network then things are a lot better, but external services are highly variable based on how the route traverses the virgin network.
