Million Instructions Per Second (MIPS)
Definition - What does Million Instructions Per Second (MIPS) mean?
Million Instructions per second is a measure of the execution speed of the computer. The measure approximately provides the number of machine instructions that could be executed in a second by a computer. Until computer speeds reached gigahertz speeds, million instructions per second was a popular measure or rating for a computer.

Instructions might take time based on different factors like input output/speed, memory, storage capacity, processor architecture, or programming language used. This often results in a computer performing faster with a lower million instructions per second rating than with a computer which has a higher value for same. Again, this benchmark is incapable of providing the information of how the processor works and whether it is suited for a particular application or not.
Million instructions per second is however useful in comparing the performance of processors based on similar architecture. It can give a clear picture of task performance speed rather than just instruction execution speed.
Again, there is no standardized method available for providing the measurement. As a result of the given reasons, million instructions per second measures are not used much.
