Maximum Possible Hit Ratio

Shown in Figures 3-7 (plotted over a period of time). HR varies from 20% to 98% and WHR from 12% to 98%. Used to determine MaxNeeded cache space.

Removal Policy Comparison

For each policy, plot ratio of HR and max HR. Use cache sizes of 10% and 50% of MaxNeeded.

Found that SIZE always outperforms other policies for HR, but is always the worst for WHR. Don't show WHR results!

ATIME is never best or worst. They believe that it is not a good server (secondary?) because client-side caching removes temporal locality. Not clear how much secondary caching is going on.

NREFS and ETIME generally perform worse. <PREV> <NEXT>
