Again, in Germany most (probably all) Cable Providers build up their networks so that those bottlenecks are not occurring.

At home I am using ISH (UnityMedia) 6MBit and I never noticed that the speed dramatically reduced. Even in peak hours the speed was always great. I know many other people which are using cable too and they never noticed those bottlenecks.

Something to remeber:

Most Providers do traffic shaping, which means, more than the limit isn't possible and the rest will be cutted!

in the past i had a ADSL and Cable Line and for testing porpouses i tried load balancing, but the speed was'nt doubled (5 MB + 5MB), i reached a maximum of 7 MBits instead of 10MBits

Reason: Cable is a star topology network and therefore if much users are online there on the same headend the speed will be dramatically reduced, while this doesn't affect ADSL (which is normally separated)

However: after changing completely to Cable 10Mbit everything worked fine and my ADSL was obsolete.
