Hardware Prefetch training on Software Prefetch
NOTE: This option is available on G7 servers with AMD processors.
The processor assists and calibrates with software prefetching (also known as predicting)
technologies for better use of system memory when using applications that manage or request the
same kind of information frequently. This option controls those 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.
Options include:
•
Enabled (default)
•
Disabled
