The recent Ofcom report on broadband performance shows the same thing - Plusnet's latency is, on average, a slight but noticeable notch lower than BT's.

However, Plusnet's speed is a slight, but noticeable notch below BT's.

The former is, I suspect, better routing of Plusnet's links into London. The latter is an impact of Plusnet's internal decision to apply their own profile to downstream connections. IIRC, this lops around 2Mbps off download speeds when sync'ed at 80Mbps.

DLM is pure stupidity. It's just looking how many errors before DLM do something on the line.

FTTC are suppose highest speed. Not [censored] happy about it.

Pete, yeah I know virgin media don't do DLM. But, they do have awful congestion thought.

No DLM for me.

My FTTC seem to get worse under DLM reduced from 79999K to 72000K and now reduced to 67312K as the downstream SNR reduced from 12.2 to 7.4 and interleaving INP 6.00.

max I am afraid that snr reduction is probably not DLM but new crosstalk.

What was the max downstream rate yesterday?

Haven't you got an 150Mb Virgin line??

Did you finally move to TalkTalk (gulp) ADSL2+ and get DLM switched off?

max it looks like the snr increase is probably DLM capping your speed

No, I get rid of it last February because it heavy congestion in my area for cable broadband.

yep, look like crosstalk in place!
