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.
