Analysis causes slow speed of network

One, the network exists the loop to cause the net speed to become slow

This phenomenon rarely occurs when the number of nodes involved in the network is not many and the structure is not very complex. However, in some more complex networks, there are often redundant lines, such as inadvertently connected to form a circuit. For example, cable from the network Center to a computer room, and then from the computer room to the second room computer. At the same time from the network Center and a standby line directly connected to the computer room two, if the several lines connected at the same time, the formation of the circuit, the packet will continue to send and verify data, thus affecting the overall speed.

Second, network cable problems caused by slow speed

Third, the network of a port to form a bottleneck resulting in slow speed

Routers wide area network ports and LAN ports, switch ports, hub ports, and server network adapters can all be bottlenecks.

Four, network equipment hardware failure to cause slow speed

Five, the virus influence causes the network speed to become slow

Vi. excessive use of firewalls

Excessive use of firewalls can also lead to slower network speeds, unloading unnecessary firewalls.

Vii. Lack of system resources

Loading too many applications running in the background leads to insufficient resources
