WebLosses can also be reduced by tuning the prefetching degree or distance. Sequential prefetching with adaptive degree was first proposed in Dhalgren et al. [10], on multiprocessors, focusing on prefetching usefulness. Adaptive stream prefetching is explored in Srinath et al. [11], balancing usefulness, timeliness and pollution.
