1. Check whether the network card speed and working mode are specified (change to auto-negotiation or a speed mode that both ends can support);
2. Whether the rate of the peer device matches the network card. The electrical port network card defaults to auto-negotiation mode and will adapt to the lowest rate at both ends;
3. Check whether the twisted pair cables comply with regulations, whether they are correctly wired, and check the cable quality (for example, 10G uses network cables of Category 6e or above or above, etc.);
4. If it is a multi-port network card, set the speed and working mode of two network ports to auto-negotiation, and use a confirmed cable to directly connect the two network cards to see if the speed is normal.
There are many factors that affect the copy speed between machines, such as the hard disk read and write speeds at both ends of the connection, platform processing capabilities, file types, and intermediate node forwarding capabilities; even the operating system will have an impact. You can use the network card to test directly. Use tools such as Iperf to test the speed of the network.

1. Too many software programs are installed and running on the computer, causing too many computer resources to be occupied, which affects the computer's running speed and is relatively slow;
2. There are too many junk files in the computer operating system and too many disk fragments, which affect the reading and writing of hard disk data;
3. There is a problem with the local connection settings (IP settings, DNS settings, etc.);
4. Gigabit causes slow connection during the process of adapting to 100M or 10M.
