What is the best DL Speed on FTTC

Hi Guys
Im Currently Sync at 38717 / 10000 when downloading on steam / Torrents etc im Achieving 4.4 - 4.7mb/s dl i have only ever had 5.0mb one or 2 times if im not mistaken my actual speed is around 36-37mb based on 4.4/4.7 just woundering if anyone actually get the full 40mb and what speed that would be when downloading on steam or torrents ?

38717 is currently the highest profile you can be allocated. There are overheads in all TCP/IP data streams so 36-37 Mbps is not to bad. There are all sorts of other factors which need to be considered too, such as network congestion.

Are you aware of the difference between Megabits per second, (Mbps), and MegaBytes per second, (MBps)? Only the b/B distinguishes them, but in your post you only use "b".

The connection speed and IP Profile are in Mbps. File downloads, torrents etc. are usually shown as coming down in MBps.

There are 8 "bits" to a "Byte". So if you are getting 4.7MBps (MegaBytes) per second that is 37.6Mbps (Megabits) per second, which with an IP Profile of 38717Mbps is extremely good. You seem to have that sussed, from what you say, just the use of "b" throughout your post is confusing.

A reading of 5MBps would mean something is telling you fibs. It isn't possible. Though some speed tests, (so perhaps some torrenting software), can give impossibly high readings - this is usually due to buffering within Internet Security suites in between the actual download and presenting it to your computer, as it can build up a wodge that gets released at higher speed inside your computer.

How often do you receive these speeds while downloading? I also sync at 38717 but have never received near 4MB/s . The last time I did was nearly a year ago. Just thought it was most servers not giving enough but I may have a problem =S. Thanks

There aren't too many websites that can support the full download speeds of 4.4 - 4.6mb/s. I tend to find it's only sites like Nvidia, Microsoft, Apple etc that give the full speed consistently.

The majority of websites seem to let you download at around 2 - 3mb/s. Newsgroups also work at full speed 24/7 for me.

My torrent sites i alway get 4.0MB/s + and on steam same when dowloading from big names like microsoft / EA etc my snc has never change from top sync since i have had it i was just curious to see if anyone had better. anyway im on aquiss and had no issues and anything was better than 3.5 mb i was getting on sky

No, 38717 is the IP profile www.speedtester.bt.com is reporting. To have this profile, you are sync'd at 40000Kbps.

Or close.

So far as I know my modem is still on its engineer-tested connection of 39992kbps and have 38717. I've seen someone else claiming the JDSU showed a bit more than that under 40000kbps and they too have 38717.

That's just minor nit-picking though.

Or is my memory incorrect? I could have sworn his tests were JDSU >> modem >> socket? Am I false-remembering?

The most reliable site for d/l testing IMHO is www,heanet.ie where many linux distros are located as well as it being a scourceforge mirror. Maxes out my FTTC connection @ 3.6 MB/s. Very reliable indeed. Also, I have to say the with an always on connection, beit ADSL or fibre, it is very important to have a continual download meter visitble. Without it on might think one's connection is working fine.

Nah, Bob, the JDSU connects on the end of the RJ11 lead. Funnily enough, mine will often show less than 40000Kbps at the cabinet (especially on cold mornings). But the Eclipse test with the VDSL modem in sync, shows a higher sync.

OK .

I certainly saw 39992 on the JDSU, but to someone seeing this for the first time there was an awful lot going on.

So are you saying that it has to be the full 40,000kbps to get 38717, or is there a bit of leeway, as per an ADSL(1)/ADSL2+ IP Profile? (Scroll down to the 7968/8128 point, as around there didn't change when ADSL2+ was added).

I have to say that I entirely disagree with this, obsessing over connection speed on a cheap residential service isn't worthwhile. As speeds increase contention will, necessarily, increase as price isn't going up to match and preserve the same ratio.

Some drop in speed at peak times is the connection working fine. If it starts affecting performance to the extent where things feel less responsive this will be noticed, if it's dropping from 3.6MB/s to 3MB/s on a download with zero change in latency or responsiveness on interactive tasks it's hardly worth giving screen real estate to to notice. The speed meter on the browser / FTP client will show download performance in any event.

Perhaps I'm not demanding enough?

Be that as it may, the question and the bulk of your reply are about throughput. Your "obsessing over connection speed on a cheap residential service isn't worthwhile" confuses the issue , as I presume you don't mean "connection speed".

In my case, I have Networx running continuously in my new life on an allowance-based service, with the speed graph showing most of the time.

The speed graph is of purely academic interest except when doing a very rare 100MB+ download or when doing a speed test. In both those cases it does give a reasonable view of the combination of my ISP and BTW backhaul performance, and in the case of a speed test gives a guide to the veracity of the result.

So really, I suppose that adds up to agreeing with you. Just been at the red wine again so being nit-picky.

So are you saying that it has to be the full 40,000kbps to get 38717, or is there a bit of leeway

Pretty certain that it doesn't have to be 40000kbps. The OR engineer said he got 39995 on the JDSU and hunting around the Andrews&Arnold logs there are two figures which might be the sync speed - 39712kb/s and 39879000b/s but I have a 38717kb/s BT profile.

It is not just about speed. Speed changes and rate of change can be informative.
