While the use of a pipeline can improve performance, why might longer pipelines degrade performance? Longer pipelines always result in worse performance compared to shorter pipelines. A longer pipeline means each instruction must be broken into a larger number of stages. As a result, the microprocessor spends more time loading instuctions into the pipeline rather than actually execute instructions. Fewer pipeline stages improves performance. If the microprocessor predicts and loads the wrong set of instructions into the pipeline, it will take longer to clear out a longer pipeline, load the correct set of instructions, and begin executing instructions again than a shorter pipeline. Longer pipelines always result in better performance compared to shorter pipelines.
