Upstream bandwidth would be always high with full duplex connections when compared to half duplex ones. Data needs to be flowing in both directions, from user to the network and network to the user. A half duplex connection delivers upstream and downstream data flow, but this never happens at the same time. Its just one at a time. When it cones to full duplex, you can find it both happening at the same time.
Upstream bandwidth is very important just as the downstream data flow for a fewer cluster of people. I say this because most people are concerned only about downstream data flow, they don’t have much going up the pool. But still lot are really concerned about upstream data flow, people who got loads of uploads and hosting every day, and any of these would need a considerable upstream bandwidth maintained. Now how about online gamers, what about the Counter Strike lunatics?, 32 fellas moving stealth all around the “de_dust”, killing or get killed. They don’t really appreciate any latency happening out of a bad upstream bandwidth, must say they don’t tolerate that. So upstream bandwidth is really important and few ways you can check you are delivered the available best.
Increasing the Upstream Bandwidth is easy to be doing, first you can check with your ISP and get known to your bandwidth and connection plan, next check your connection speed with Speedtest. Now if you are running low, you can check if your computer got any problems. Follow the article on How To Increase Bandwidth and fix possible problems, if any.
