Question

Select one or more of the following statements that correctly describe the performance implications of doubling the size of a buffer in an output device or device controller.

If the previous buffer size was relatively large, the performance improvement resulting from doubling its size may be offset by the cost of the additional buffer capacity.

The performance improvement may be much less than 2x due to diminishing rates of return on increased buffer size.

Double the number of interrupts will traverse the system bus for all data transfers through the larger buffer.

All data transfers through the larger buffer will occur in half the time of data transfers through the smaller buffer.

Explanation / Answer

The answers are options A, B, D

Higher buffer gives the computer more time to process the data. Lower buffer spits out the data
faster, but make the computer work very harder.
