Upload speed on fibre

[#1]

I have fibre broadband (+phone fwiw) and the upload speed limit was previously stated as (upto) 2Mb, and I was getting around 1.6-1.65Mb. Your website now says upto 9.5Mb, yet I still get the previous 1.6-1.65. Is there some small print issue here, or some config needed to get (close to) the advertised figure?
Thx
