An Analysis on the Web Technologies for Dynamically Generating Web-Based User Interfaces in Ubiquitous Spaces

摘要

In this paper, we study the web technologies that allow ubiquitous spaces to create dynamic web pages in accordance with user profiles. Especially, we explore the server-side scripting approach, the most popular technology for dynamic web pages. This approach mainly adopts the execute-while-parsing model, which suffers from the interpretation overhead. Recently, the compilethen- execute model was proposed to address the overhead. This paper compares and analyzes the two models, while performing benchmark test in Microsoft ASP and ASP.NET environment. The benchmark results show that, due to the high initialization overhead, the compile-then-execute model cannot substantially improve the execute-while-parsing model. Also, the best performance can be achieved through optimization rather than compiled execution. Based on the results of the benchmark test, we develop a speedup model, which estimates the maximum performance improvement achievable by the compile-then-execute model.
