Delphi connection through the TNMEcho component velocity test network speed, and can detect the current network transmission speed, by sending a string data, designated IP, according to the time of return measured speed. There is a TNMEcho component in Delphi, use it to the Echo server to send some data, the data is returned from the Echo server, and then to calculate the time difference, you can roughly calculate the network connection speed. The test speed can be used as a general reference.
