Generally, China Unicom’s 10M is just a pseudo 10M. The download can reach the speed of 10M bandwidth, but the upload channel is still about the same as 2M. This situation can easily occur if someone uses some software with a large upload volume. Another situation is that China Unicom's switches are relatively old. Regardless of whether the network speed is 10 Mbit/s during peak periods, the switches only have such a small capacity, so it is strange that the network speed is intermittent.
