what blocking mode

In the thread blocking mode (tthreadblocking) of the tserversocket in DELPHI6, The onread/onwrite event is executed in the main thread. Although it is multi-thread, the actual efficiency is not high.Therefore, if we need to use tserversocket to

Because the application level does not use multithreading, this causes the application to handle the socket socket one-by-one. This socket socket does not finish processing, you can not handle the next socket socket. The problem can be improved by
