....whereas prefetching using NPS decreases response times by 25 . 1 Introduction A number of studies have demonstrated the bene ts of web prefetching [12, 17, 24, 25, 32, 33, 42, 52] And the attractiveness of prefetching appears likely to rise in the future as the falling prices of disk storage [14] and network bandwidth [41] make it increasingly attractive to trade increased consumption of these resources to improve response time and availability and thus reduce human wait time [7] Despite these bene ts, prefetching systems have not been widely deployed because of two concerns: ....

....interfere with other services, and if they are too timid, prefetching services will not gain the bene ts they might otherwise gain. Fortunately, there is reason to hope that performance will not be too sensitive to this parameter. First, disks are large and growing larger at about 100 per year [14] and relatively modest sized disks are e ectively in nite for many client web cache workloads [52] So, disk caches may absorb relatively large amounts of prefetch data with little interference. Second, hit rates fall relatively slowly as disk capacities shrink [5, 52] which would suggest that ....
