Abstract

In this report we compare the performance of a prefetching page server system with a prefetching object server system. We simulate the object access pattern by assigning transition probabilities to the object relationships. According to the transition probabilities we compute the access probability of pages and objects. We designed several prefetching techniques for a prefetching page server and a prefetching object server. We compared the performance of the prefetching techniques in a simulation.

Keywords
