I have a 35/35 connection that I regularly saturate, and unfortunately it's the best available. (Frontier offers better service elsewhere, but not here.) I don't saturate it 24 hours a day, but when I use it, I use all of it. For the download bandwidth, between videos, large packages, and source code, the limiting factor is almost always on my end. And for upload, I use it with VPN, with regular backups, with git, with scp, and with rsync. I would love to have a gigabit connection to see if that connection would still be the limiting factor, and I suspect it still would be sometimes.
