> I do think 25Mbps up is more than what's required for a large number of households (>33%). I have advised family that 15Mbps is adequate when they needed to do office work from home.
Yet my experience when streaming high def video is much better in places with symmetric fiber with much higher upload bandwidth (> 100Mbps) than it ever is in places with coaxial cable bandwidth.
TCP ACKs back up are needed even for downloads and can get crowded if the bandwidth in that direction full or crowded. If those tiny ACKs don't get through downstream may stall. Linux QoS can help, but only if your router is Linux and you can run the appropriate commands on it.
