In Computer Architecture, performance measures are used to evaluate the efficiency and effectiveness of a computer system. Here are some of the most commonly used performance measures:

1. **Clock Rate**: This is the speed at which a microprocessor executes instructions. It is measured in Hertz (Hz). A higher clock rate means the processor can execute more instructions per second, thus increasing the performance.

2. **Instruction Count**: This is the total number of instructions executed by a program. A program with a lower instruction count will generally run faster than a program with a higher instruction count, assuming the same clock rate.

3. **CPI (Cycles Per Instruction)**: This is the average number of clock cycles an instruction takes to execute. A lower CPI means that instructions are executed more quickly, thus increasing performance.

4. **MIPS (Millions of Instructions Per Second)**: This is a measure of the number of instructions a computer can execute in one second, expressed in millions. A higher MIPS rating means a computer can execute more instructions per second, thus increasing performance.

5. **FLOPS (Floating Point Operations Per Second)**: This is a measure of a computer's ability to perform floating point operations, which are often used in scientific and mathematical computations. A higher FLOPS rating means a computer can perform more of these operations per second, thus increasing performance.

The criteria commonly used to evaluate the performance of computer systems include:

1. **Speed**: This refers to how fast a computer can execute instructions. It is often measured in terms of clock rate, instruction count, CPI, MIPS, or FLOPS.

2. **Throughput**: This refers to the amount of work a computer can do in a given amount of time. It is often measured in terms of tasks completed per unit of time.

3. **Efficiency**: This refers to how well a computer uses its resources (such as CPU time, memory, and disk space) to perform tasks. It is often measured in terms of the ratio of output to input.

4. **Reliability**: This refers to a computer's ability to perform tasks without errors or failures. It is often measured in terms of mean time between failures (MTBF).

5. **Scalability**: This refers to a computer's ability to maintain performance as the workload increases. It is often measured in terms of how performance changes as the number of users or tasks increases.
