Abstract With the development of high-speed backbone network, more and more traffic load is pushed to the Internet end system. The satisfactory execution of common business applications depends on the efficient performance of web server. In this paper, we propose a pipeline multi-thread kernel web server open KETA which divides the processing of a request into several independent phases. This architecture reduces parallelism granularity and achieves inner-request parallelism to enhance its processing capability. Furthermore, a thread allocation model is used to manage threads effectively in this special architecture. This model can adjust the thread allocation based on the server load and the work character of each phase so that the thread resource of web server can be utilized properly. Experimental result shows the capability of this web server and the effectiveness of the thread allocation model.KeywordsQueue LengthData CacheManage BufferTask ListHelper ThreadThese keywords were added by machine and not by the authors.
