Taking a Sudoku solver as an example, this paper reviews a variety of design schemes of concurrent network service programs, and introduces two common techniques for writing multithreaded servers using Muduo network library. The previous examples show Muduo's ability and convenience in writing single-threaded concurrent Web service programs, and today we look at its performance in multithreading.
