The PHYSBUFF configuration parameter and memory utilization

The PHYSBUFF configuration parameter determines the amount of shared memory that is reserved for each of the two buffers that serve as temporary storage space for data pages that are about to be modified. The size of a buffer determines how often it fills and therefore how often it must be flushed to the physical log on disk.

Choose a value for PHYSBUFF that is an even increment of the system page size.
