If it is a new magnetic flux source, due to the low popularity, that is, there are too few people downloading, the speed will be slow at the beginning. At this time, wait for a period of time, and when there are more people downloading, the speed will increase.
If the magnetic link is too far away, even if it is too old, the download speed will not improve. At this time, if there are other sources to download, the situation may be improved.
The network environment can also affect download speed, and if the network environment is good, the download speed will also be higher.
