For example, when you download a task, if you have enough resources, you can reach the maximum of your physical bandwidth, that is, the speed of 400KB/S, but if you download two tasks, the 400KB/S will be allocated to these two tasks. The more tasks, the more points, but your bandwidth is inconvenient, so the more tasks, the slower the download speed seems to be.
If the file is in urgent need, just download one directly, which is faster.
