Why is the Internet speed slow in Internet cafes, but the network response speed is fast?

You should know that the network cable of Internet access at home and Internet café is not the same, generally speaking, there are local area Internet access (LAN) broadband (ADSL) and fiber optic Internet access, etc., the school base is based on LAN Internet (LAN), this kind of network speed is very slow, all share an IP, he directly connects to the network through the ** line, and the speed is only 20-40k s Generally Internet access at home is with broadband Internet access (ADSL) Internet speed in general. It is also a high-speed access mode that obtains IP through ** line, and the speed is generally 90 110k s, while Internet cafes use optical fiber to access the Internet, and the speed of optical fiber can reach 500 700k s. Some Internet cafes are 100 megabits, and the light in larger Internet cafes can reach gigabits, (theoretical value) Because the sensing speed of light is faster than the sensing speed of electricity, broadband Internet access (ADSL) is not as fast as optical fiber access, which is the main reason why the Internet at home is not as fast as the Internet in the Internet café There are hundreds of megabytes of optical fiber in Internet cafes, and the broadband bandwidth is only 4-5 trillion at home.

The network is a segment, that is, the data packet starts from your computer, passes through the operator module room, the aggregation room, the core computer room, the provincial company computer room, and the backbone computer room of the region, until it reaches the final **, and every link that passes through may be blocked and affect the network speed.

Generally speaking, the 10m bandwidth of the Internet café is optical fiber, and the exclusive 10m is 10M from the Internet café to the destination, and the 3M of ADSL is shared, and it may be 3M from your home to the access room, but an access computer room may have 100M bandwidth, but it has more than 500 users, and so on at the peak of Internet access, it must be less than 3M bandwidth per person on average.

3M's broadband does not provide you with 3072kbps bandwidth, the normal 3m broadband provides the ** network speed is 300kbps, and the highest 3m in my home has reached 315kbps. So don't think that your home internet speed should be faster than that of an internet café. On the contrary, the same bandwidth Internet café uses optical fiber, your home is ** line dial-up, plus the network operator blocks certain ports or protocols, and the network at home is not at all strange than the network of the Internet café.

Internet cafes generally use optical fiber, and smaller Internet cafes also have an Internet speed of 5 10m.

You can find a network accelerator to speed it up.

The server is slow and has a large number of visitors.

It might be quicker to redo the system on your own.

If you have the conditions, it is better to run naked and do not have antivirus software.

Your system has too much junk and should be cleaned up in time

The computer configuration is low and the memory is small.

Either you have a problem with your system.
