When a user browses a web page, user can wait until web page is displayed. This time is called tolerable delay time. A conventional method to maximize the number of web accesses of web page is displayed within tolerable delay time has been proposed. In general some web pages can convert ordinary web pages (ordinary contents) that you usually use to simple web pages (simple contents) reduced contents such as images. By converting from an ordinary content to simple content, the number of web accesses satisfying the tolerable delay time may be increased. However, conventional method assumed that type of content is only the ordinary content. Moreover, tolerable delay time of each content was the fixed value. In this paper, we propose a method to maximize the number of web accesses by converting ordinary contents to simple contents when the waiting time for access does not satisfied tolerable delay time. In addition, we analyze the characteristic of our proposal method by changing tolerable delay time of content.
