Despite a 50k line, only 22 mbits at download speed?

Since yesterday we have a FritzBox 7590 and a 50k line. I have just done a speed test on the laptop, but the download speed shows only 22 mbits for the download speed and only around 7 mbits for the upload speed.
Why doesn't it even reach 40mbits, even though we have a 50k line? How can I improve this?

1. Do the Telekom lines belong to which of z. B. O2 can only be rented… You should therefore consider how the price comes about when O2 is sometimes 20-30 euro cheaper than Telecom although they rent the lines

2. Are the 50K the highest value that can be achieved… The small print usually says how much most arrives or how much must arrive and unfortunately that is usually less than 50%
