Buffer Cache Statistics

SarCheck reports the limits to dynamic buffer cache size associated with the dbc_min and dbc_max_pct parameters, and if helpful, the actual range of the buffer cache size will be reported.

In this case, memory pressure prevented the size of the cache from growing beyond the minimum value.

This system's buffer cache is dynamic, meaning that its size is determined by the amount of free memory on the system. Buffer cache data indicates that increasing the size of dbc_max_pct would probably not be effective because memory pressure would prevent the buffer cache from growing much beyond the value specified by dbc_min_pct. Based on the current values of dbc_min_pct and dbc_max_pct, the buffer cache can range in size from 12.8 to 25.6 megabytes of memory.

A graph of buffer cache utilization was not generated because the size of the buffer cache hovered closely around the value of dbc_max_pct and the graph would look like a straight line.
