30M Finally had enough of VM BS........... - Page 7

I've modified the test slightly to simulate a typical high-quality VOIP connection - 100pps, 80B payload size. On your connection:

Packets: sent=1000, rcvd=1000, error=0, lost=0 (0.0% loss) in 10.029377 sec
RTTs of replies in ms: min/avg/max/dev: 20.327 / 32.502 / 53.147 / 5.985
Bandwidth in kb/sec: sent=10.768, rcvd=10.768
Out of sequence packets: 21

VM in my area:
Packets: sent=1000, rcvd=1000, error=0, lost=0 (0.0% loss) in 10.020790 sec
RTTs of replies in ms: min/avg/max/dev: 25.218 / 30.334 / 54.009 / 3.774
Bandwidth in kb/sec: sent=10.777, rcvd=10.777
Out of sequence packets: 2

BT Infinity:
Packets: sent=1000, rcvd=1000, error=0, lost=0 (0.0% loss) in 10.021413 sec
RTTs of replies in ms: min/avg/max/dev: 31.378 / 31.789 / 32.796 / 0.170
Bandwidth in kb/sec: sent=10.776, rcvd=10.776
Out of sequence packets: 0

Statistics for pingbox1.thinkbroadband.com:
Packets: sent=1000, rcvd=1000, error=0, lost=0 (0.0% loss) in 10.001254 sec
RTTs of replies in ms: min/avg/max/dev: 11.144 / 11.257 / 12.889 / 0.085
Bandwidth in kb/sec: sent=10.798, rcvd=10.798
Out of sequence packets: 0

Note the Std. Dev figures don't tell the whole story, as packet to packet jitter on VM in my area is quite low, with occasional "gaps" of 20ms+ e.g.:

Spoiler:

Yet on yours it's constantly variable but most jumps are <10ms:

Spoiler:

And despite st.dev. being less than 2x as high in your area, out of sequence packets are over 10x higher, the latter being, as mentioned, quite disruptive to VOIP communications

Before you rewrite history you might want to re-visit where you thought you last checked your official figures and place them in the correct context?
I think you might find it was more like 66% of users got within a specific percentage of the headline speed?

For example from Ofcom/SK/VM in mid 2010:

Quote:

" Virgin Media cable customers typically received speeds which were much closer to advertised speeds, with almost 90% of those on 'up to'10Mbit/s receiving average speeds of over 8Mbit/s, and 80% of those on 'up to' 20Mbit/s services receiving average speeds of over 14Mbit/s."

Of course I daren't even suggest or hint about the lack of information concerning the actual statistical sampling by node/cmts/area.
Nor anything regarding the way the actual data is "normalised"!

Not that 2+ yrs worth of data myself and 1600 other SK/VM trialists could ever be released publically anyway without VM&SK express consent.
Just to balance my implied critique - my own d/s from my latest calculations easily exceeds >90% of Max Configured thruput rate for >90% of time in one Brighton hotspot across 2 CMTS chassis.

Remembering that D/S is only 1 of a total of 10 metrics that we currently collate and probably (in my case until very recently) both the d/s & u/s were the only two more consistent measurements!

Fair enough. But the point is still valid

you think thats ok constantly variable during the morning?

To honour Mick Fisher's point about BS, VM is full of BS in other areas.

Here's what they currently say on their web site in relation to the Super Hub:

Welcome to wonderful wireless broadband
With a wireless network in your home, no-one needs to plug in with wires. That means everyone can connect to the internet at the same time using one fast, secure broadband connection â€“ in different rooms and on all sorts of devices (like laptops, smartphones or games consoles).
The best bit? All you need is a Virgin Media Super Hub, which is included with all our broadband packages.

The Virgin Media Super Hub - our fastest ever wireless- Packed with the latest wireless â€˜Nâ€™ technology for a really fast, secure - connection
- Built to handle speeds of over 120Mb
- 5GHz compatible

How fast is wireless broadband?
Don't worry - going wireless won't cramp your style. You can still do everything that you'd expect to do with a wired connection, only now you're not tied to your desk:
- Go online anywhere in the house
- Print stuff from anywhere in the house
- Get fast broadband on your mobile instead of using 3G
- Send photos from your mobile to your laptop
- Play music from your computer around the house
- Download a film onto your laptop to watch on your TV

I don't need to point out the blatant pieces of BS - surely even to die-hard VM geeks.

Go on... humour me

Sephiroth · 07-09-2012, 18:37

Why?

It gives his limited amount of brain cells something to do

carlwaring · 08-09-2012, 08:54

Well if you can't then it doesn't matter. You said there was "BS" in there. I simply asked where.

Tazz · 08-09-2012, 08:58

Well all of it is BS as far as I am concerned.

carlwaring · 08-09-2012, 09:14

Fair enough. Most marketing is a certain amount of "BS" (if you want to put it like that.)

However, I think the rule it is must not actually be lies. So, if there are any in what VM have said then by all means report them.

If not, remember it's just marketing

If you have a reasonable point to make then insults are not necessary to carry on friendly discussion.

There should have been no need to ask. But the wretched thing is hardly "packed with the latest wireless N technology". This "5 GHz compatible" euphemism is BS. It is hardly packed with the latest stuff if it isn't dual band.

Incidentally they've reworded this in recent days; it used to say "jam packed ...". Of course the mind sticks the "jam" in front so it is delusional. They've also taken out other unsustainable claims. But it's still BS because they shouldn't be providing this piece of junk except as a modem.

They Bs-ingly say elsewhere:

Virgin Media Super HubThis combined modem and router gives you an ultra strong signal throughout your home

That is the ultimate piece of BS. The SH does not provide an ultra-strong signal throught the home. It can't - it's got two postage stamp sized antennae (instead of six normally found on un-slugged routers) at the bottom rear of the wretched thing. It doesn't matter what a VM geek has to say about his/her wireless signal, the reports of objective, honest people on the various forums make it quite clear that VM's claims for this wretched device are BS.

That you needed this spelling out says a lot about your own delusions on the subject.

OK the title of this thread may appear open ended BUT that does not mean that those participating in it may bait and troll to their hearts content.
