I noticed with 2mbit I could cap my upload to 80-90% and it had no affect on download speed. With 10mbit if I cap to say 30kB (50%) I lose about 25% download speed around max 7-8mbit, I actually have to cap to 20kB or lower for it to not have an affect. You need to remember if you have upgraded from say 2mbit then you have a increase of around 150% in upstream but 500% in downstream so the % of your upstream capacity needed for acks is now higher.
