Value Meaning
0 The system calculates an optimal value for this entry based on the amount of physical memory on the computer, and adjusts this value if the amount of memory changes. This value is optimal for most systems.
1–128 Overrides the value calculated by the system and prevents the system from adjusting this value dynamically. This setting can degrade performance.

Caution Image Caution
