Adjacent Sector Prefetch NOTE: This option is available on servers with Intel processors. This option controls processor prefetch features. In most cases, this option should remain enabled. With certain workloads, however, disabling this option may provide a performance benefit. Disable this option only after performing application benchmarking to verify improved performance in a particular environment. IMPORTANT: Disabling this option is not recommended because it typically degrades system performance. Options include: • Enabled (default) • Disabled Advanced Options menu 117
