Throughput vs. Sync Rate for Different ISPs


[link to this post]
 
TalkTalk staff tell their fibre customers that: throughput speeds are usually 80% of the sync speed

Is that a standard fibre stat or is it dependent on provider?

Does it mean for TT customers with a perfect line delivering max synch on the 80/20 product that throughput won't be above approximately 64meg (80% of 80)?

More rubbish ... they say it to fob people off when their speeds are slow and there is congestion. Train them at day one and it will perpetuate!

The max throughput is over 95% of Sync (cannot remember the exact figure - 96.8% I think) and with no congestion you should see that figure or very close. Even with a small amount of errors and resends you will still be up at 95%.

For a "perfect" line on 80/20 you should be seeing 76Mbps - the figure BT now uses.

Ummm?

Your 96.8% sounds like the BT Wholesale IP Profile of 96.79% on non-G.INP, and your 76Mbps the Ofcom imposed figure for the sync 10% of customers can achieve. Neither of which refer to throughput.

Throughput may be being quoted from speed tests, many run wirelessly connected to the router.

We often see speed tests on these forums above 74mbps, but 76Mbps?

They're telling you porkies. On TT I sync at the full 80/20 and speedtests show 75/18 meg day and night...with no sign of any congestion whatsoever smile

with full sync

BT - 74.82Mbps
Talktalk - 75.21Mbps

Its never 80%

closer to 95%

Forgive me if I've misunderstood this, but throughput will be partly dependent on the equipment in the home? So when TT say throughput is usually 80% (which they say repeatedly to many customers on their forum), could this be TT tacitly acknowledging that their router is poor and is therefore increasing the spread between sync and throughput? Such that 80% really is the average for most of their customers, thus making the statement truthful? Otherwise it seems strange they would constantly repeat a downright lie.

Baby F, Do you use the TalkTalk provided modem/router or have you bought your equipment and are you on a normal TT domestic product or business fibre? (Also your 75meg output is great! What's your max line rate stat taken from the router?)

It's mostly just to stop people ringing them up complaining about throughput.

To be honest there are so many things that can affect throughput, some down to the user and some to the ISP (and many that are wider Internet related) that giving any figure is a nonsense. Any figure chosen is made up and not relevant to most people.

Talktalk routers that support VDSL2 can support full sync rate throughput.

If you where lucky to get a HG635 "super router" they're in my opinion one of the best packaged routers ever from an isp.

I have a HG635 by talktalk and it's the best router I have ever used.
The HG633 is also able to pull the full speeds as well.
So in essence, the router is able to support the speeds & is not rubbish.

The 10% is nothing to do with Ofcom but CAP/ASA, and relates to throughput not sync.
