empirically determining a marginal utility of adding space to a random list; and

based on the determining and Empirically determining acts, dynamically establishing a desired size of the sequential list, wherein the logic executes the empirically determining act by determining the rate “s” of sequential misses as the number of se sequential misses during a time period defined by two successive cache hits in a bottom portion ΔL of the random list, and further wherein the system executes logic comprising:

moving at least one newly prefetched group of units of data along with an asynchronous trigger unit of data in the group of units of data to a most recently used (MRU) portion of a sequential data list; and

moving at least some unaccessed units of data in the group of units of data to the MRU portion of the sequential data list.
