There are several reasons for the slow network speed: First, the network itself (insufficient bandwidth or excessive load on the server). Second, the network cable problem leads to slow network speed (twisted pair is not up to standard, which is manifested as: in one case, the network speed is very slow when it is first used; In another case, the network speed was normal at first, but after a while, the network speed slowed down. Third, there is a loop in the network, and the network speed is slow. Fourth, the broadcast storm caused by the hardware failure of network equipment slows down the network speed. Fifth, a port in the network has formed a bottleneck, slowing down the network speed. Sixth, the influence of worms causes the network speed to slow down. Eighth, excessive use of firewalls. The lack of system resources is mainly caused by the above reasons. Personally, I suggest you clean up the garbage process of your computer and optimize it. ★ Copyright statement: This answer was originally written by /tp Ren Wei /aiq, and no one may steal it. Thank you for your cooperation! ★ Solution: First, please change the time or change the target website. Second, check whether the twisted pair is qualified. Thirdly, the method of partition and segmentation is adopted to gradually eliminate loop faults. 4. Test the involved computers one by one with the "Ping" command under DOS. Network cards, hubs and switches are the most likely devices to fail and slow down the network. 5. Replace the server network card with 100M or 1000M, install multiple network cards and divide them into multiple VLAN, and change the router configuration to increase the bandwidth. 6. The anti-virus software used must be upgraded in time; Computers should also upgrade and install system patches in time, uninstall unnecessary services, and close unnecessary ports to improve the security and reliability of the system. If you can solve these problems, your internet speed will be fast!
