Slow download speed compared to line speed

Since moving onto the ADSL2 trial I don't seem to get a download speed that represents the line speed I am connecting at.
My router has connected as follows (I asked for upstream to be reduced):
Upstream 444
Downstream 4076
SNR Margin(Upstream) 9.6
SNR Margin(Downstream) 6.0
Line Attenuation(Upstream) 38.7
Line Attenuation(Downstream) 58.5
When I run a speed test at http://www.mybroadbandspeed.co.uk/ I get download 2721 and upload 375. This seems to be what I get when downloading too - around 2.7 Mbps.
Why am I not getting closer to 4Mbps?
Cheers,
Gary.

Out of interest, are these speeds at peak times? I've got another thread on this and have had some help that seems to have improved things, but it's still way below sync. The issue as I understand it is congested exchanges for 21CN. One would hope this would improve with investment in capacity, especially as BT are rolling this out to their customers as otherwise it will just get worse!

Strangely the download speed I'm getting is identical to when I was on ADSL1. So with ADSL2+ I get about 1Mbps extra line speed, but no extra download speed?!

You may alsso need to run a BT Speedtest to find out what your line is profiled at by BT. The BT & PN figures should match.
I've just checked mine since moving to ADSL2+ on Thursday and my PN figure currently isn't aligned with BT's - infact it hasn't moved from my old line profile.
@Jameseh: Any chance you could nudge mine in the right direction if you read this!?

I was upgraded to ADSL2+ on Tuesday so it took a while to change.
I don't seem to have many (if any) disconnects - the connection seems very stable. I thought the first few days it trained and tried different speeds? Any way I can force it to try to connect at a slightly faster speed?

Your profile on our side matches the BT one at 3500 now, have your speeds changed to show that increase?
@Paul03
I'm taking a look at yours now.

There was a missing piece of information on your account from when you moved to ADSL2+, hence our system not picking up the correct profile. I've updated this and the profile now matches with the BT one at 2000.
