Slow Single Thread Speed


[link to this post]
 
Hi all,

Anyone else have single thread speed problems? Have just joined Sky from BT and am only getting just over half of what I should be. No such problems while on BT. Any ideas on what's going on?

Connection Speed 39994 kbps 9995 kbps
Line Attenuation 17.1 dB 18.0 dB
Noise Margin 12.0 dB 12.12 dB

What product were BT providing ? Looks like Sky have you on a 40 meg service.

Thanks for the reply. It was 80/20 Infinity 2, but I was syncing at about 67/20. Sky is 40/10 service.

So that looks kinda OK, sync rate wise ...

a bit surprised you didnít get pretty much full sync on a short line like yours .....

are you connected in the NTE and filtered properly ?

Iím connected to a filtered faceplate. The type that were installed when FTTC first came out.

I did get full sync on the BT 80Mmb service when first installed, but that slowly went downhill over the years. I assume because of crosstalk?

The Sky fibre is connecting at full speed though (or near as damn it), just canít understand why the single thread speed is so bad on speed tests? As I say no such problem existed when I was on BT a few days ago.

If you have the Sky Q hub, depending on your setup this might be entirely by design. The Sky Q Mesh network does not always provide a device full speed single thread unless absolutely required where there are other devices connected. If you fire up a 4K stream, that needs 30Mbps, you'll see it releases the speed. Sky Q works well when you don't focus on all the details, since the Sky Q Airties setup is quite complex.

Thanks for the reply ukhardy. It is a Sky Q Hub, but donít have Sky Q for TV (still on 1Tb Sky HD box), so no mesh network.

Is the test over WiFi? If so you really should check with a cabled Ethernet connection to ensure the WiFi isn't impacting on the results.

Thanks for the reply Ian. That particular test was over Ethernet. Tbh the difference between WiFi and Ethernet is negligible. Small house, good WiFi signal everywhere.

OK, that rules out WiFi - WiFi can be an inhibitor so good to rule out - it also would rule out the mesh theory anyway as you weren't using WiFi and the mention of mesh was the reason I asked.

It does look like congestion somewhere, probably in the Sky network.
