HW Prefetcher
Use this option to disable or enable the processor prefetch function. In most environments, leave it
enabled for optimal performance. With certain workloads, disabling this option might provide a
performance benefit. Do so only after performing application benchmarking to verify improved
performance in a particular environment.
NOTE:
This option is available on servers with Intel processors. Disabling this option is not recommended
because it can degrade system performance.
