This semester, the dormitory network has been upgraded, and the speed is as high as that of the map, but it is actually only a few hundred K, and occasionally downloads several megabytes per second for two days. The network speed test is generally only a reference, and there are many factors that affect your network speed, especially the campus network, because everyone shares IP. Therefore, it is normal for the values to be different. There are several factors to refer to.

1+000 m network speed bandwidth allocation, from telecom or netcom to home (that is, into the campus) may be 100M, but the campus is divided by switches and routers, and there may be 20 dormitories. 100 people use this 100M broadband, so everyone's bandwidth is only/kloc-.

2. Download speed is related to resources. For example, the picture you downloaded is in a server, and its bandwidth is 1M, and yours is 100M, but the download speed is based on 1M, which is why we sometimes get stuck watching movies when the bandwidth is enough.

3. Download tools are related to the number of users, especially download tools such as Thunder, Cyclone and Express. Their principle is that Zhang San downloads A, Li Si downloads B and Wang Wu downloads C, which takes up less original resources. Zhang San downloaded A, and everyone went to Zhang San to download A, and then to Li Si to download B. Later, all download users became resource users. When you only download yourself, all your files are downloaded from the server, which is definitely much slower than * * * *.

4. Network resource allocation restrictions, such as the overall bandwidth is m, QQ allocation is 1m, video allocation is 2M, and download allocation is1m.. The more software you use, the more bandwidth you allocate. This is why we often see settings such as download priority and internet priority when setting Thunder. Once resources are allocated, it is normal to download pictures slowly.
