Download speed is lower than I would perhaps expect?
« on: December 21, 2021, 05:25:10 PM »

Before I start, this is not a complaint and it is something I don't much care about but I am curious as to the reasons behind it.

My stats are as follows:



I was expecting to see a download speed of around 70Mbps but the most I seem to be able to get is about 60, can anyone explain why this might be?

I'm on TalkTalk.

I'm no longer on TalkTalk but I found my line capped around 60000kbps.

How are you measuring it?

Your sync looks similar to mine, Talktalk seem to leave me on a 4db profile:
Code: [Select]
Sync Status In Sync
Downstream Speed (MBPS) 76.0
Upstream Speed (MBPS) 20.0

What's your upstream sync at?

Sorry for the delay. Used a variety of speed test sites wired into the router. And 60Mbps is about the maximum.

Sync speed is now 79999 so the maximum and I am still capped at 60.

Any ideas why?

20Mbps and download is now 79Mbps (sync speed), what speed can you achieve?

Okay update, now been able to get up to 67Mbps but this still seems like it's capped? Any idea, should be able to get into the 70s no?

I can achieve the full 80/20, though Talktalk seems to cap me at 76/20.

I'm moving to a Gamma BTW SoGEA on the 11th as I'm sure Talktalk are stopping at a 4db profile when my line is capable of 3db.

Does 3Mbps really matter that much?

Think you are missing a 1, 13Mbps makes a difference.

13? No it doesn’t but I’m more curious as to why this is

Yes, apologies for the missing 1.

Anyway, have you tried different filters? With my ADSLNation filter I get a better connection rate (higher) than with Openreach's own MK3.

When you test one filter against another, you have to do repeated tests to account for the natural changes in sync rate due to BT’s DLM. See https://forum.kitz.co.uk/index.php/topic,15905.msg295889.html#msg295889

That would change the sync rate. They are already synced at the package maximum.

It's the throughput that is the issue. No filter is changing that.

Yes sync is already maxed out. I just find it curious that I seem to be capped just under 70Mbps
