NTL Speeds and Throttling

[glenhill]

Hi,

I have noticed since the weekend my internet experience is alot slower and any downloads aren't nearing anywhere what they use to.

I ahve the 2mb line and when I go to speakeasy to do a speed test it does register around 1.9mb.

Anyone else having similar problems?

Nope. Click the Speed Test in the NavBar at the top of the forums and paste your results here

Mine seems about right.

1st 512K took 4407 ms = 116.2 KB/sec, approx 957 Kbps, 0.93 Mbps
2nd 512K took 6379 ms = 80.3 KB/sec, approx 662 Kbps, 0.65 Mbps
3rd 512K took 4286 ms = 119.5 KB/sec, approx 985 Kbps, 0.96 Mbps
4th 512K took 6119 ms = 83.7 KB/sec, approx 690 Kbps, 0.67 Mbps

Overall Average Speed = approx 824 Kbps, 0.8 Mbps

1 Mb/s connection.

2nd 512K took 1594 ms = 321.2 KB/sec, approx 2647 Kbps, 2.58 Mbps
3rd 512K took 1843 ms = 277.8 KB/sec, approx 2289 Kbps, 2.24 Mbps
4th 512K took 1829 ms = 279.9 KB/sec, approx 2306 Kbps, 2.25 Mbps

Overall Average Speed = approx 2241 Kbps, 2.19 Mbps

now you know why I kept my profile to 2meg.

These results appear to be rather fast: maybe this page was in the browser cache.

notes the .nl 10mbit server is under load I only checked on the last test but was pushing 700kB out so when I got my 400 it would have been maxed.
the .uk server was only pushing 1mbit so max possible was 9mbit
both 100mbit servers were capable of a 10mbit xfer.
steadfast is over my much loved level3 and is nearly always poor to my connection.
the telia and .nl were both obviously faster at 12.15 and my shaping suspicions have been for .eu traffic to manage peering saturation.

Interesting results.

Well thankfully i will not have to suffer this much longer, I am now waiting for my BT line to be activated and then i can see if BE are ready in my exchange. upto 24 meg unlimited at £24.99 beats upto 2 meg unlimited at £24.99. "i expect to get about 11 to 14 meg on the connection as i am 2.3 km from the exchange". 10 meg 75gig for £34.00 just does not cut the mustard.

do these speed results prove traffic shaping is happening?

Dunno about throttling, but here in south Manchester we've also been experiencing slow access for at least a week - vv slow on Tuesday night - sites taking long time to respond or giving timeout errors (including cable forum ..).

Speed tests are all showing either 1.9 Mb or >2Mb on a 2Mb line so presumably no real problems once a connection is made.

Is this a network problem or a contention issue?

Cheers,

Pete

Looks pretty acceptable to me. As long as it's >5Mbps then it's probably worth the extra tenner a month. Not sure though...

[etccarmageddon]

tuesday night's problems were down to a denial of service attack on the NTL servers.

Ive had enough of south manchester ntl, someone wants throttling thats for sure.

Maybe they should use some of the extra money they will now be extracting on there customer service phones lines to buy some more equiptment. Its ok those of you that jump stright in and say my connection is this good, Might it be there are not that many users on your UBR. Come to my area and see if you get the same speeds. I have just about had enough of paying for a service that is in my area going down the pan fast.

Bill, I'm not sure if you're on Warrington or Stockton Heath but there's plenty of info over at SamKnows:
