2. Computer performance - Wikipedia

   en.wikipedia.org/wiki/Computer_performance

   In computing, computer performance is the amount of useful work accomplished by a computer system. Outside of specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions. When it comes to high computer performance, one or more of the following factors might be involved:

3. Speedup - Wikipedia

   en.wikipedia.org/wiki/Speedup

   In computer architecture, speedup is a number that measures the relative performance of two systems processing the same problem. More technically, it is the improvement in speed of execution of a task executed on two similar architectures with different resources.

4. Clock rate - Wikipedia

   en.wikipedia.org/wiki/Clock_rate

   The clock rate of the first generation of computers was measured in hertz or kilohertz (kHz), the first personal computers (PCs) to arrive throughout the 1970s and 1980s had clock rates measured in megahertz (MHz), and in the 21st century the speed of modern CPUs is commonly advertised in gigahertz (GHz).

   Step #3: Add more RAM to your hardware. RAM is a temporary memory used by your computer's operating system and helps your programs run smoothly.

6. Instructions per second - Wikipedia

   en.wikipedia.org/wiki/Instructions_per_second

   Instructions per second (IPS) is a measure of a computer's processor speed. For complex instruction set computers (CISCs), different instructions take different amounts of time, so the value measured depends on the instruction mix; even for comparing processors in the same family the IPS measurement can be problematic.

7. Amdahl's law - Wikipedia

   en.wikipedia.org/wiki/Amdahl's_law

   In computer architecture, Amdahl's law (or Amdahl's argument [1]) is a formula that shows how much faster a task can be completed when you add more resources to the system. The law can be stated as: "the overall performance improvement gained by optimizing a single part of a system is limited by the fraction of time that the improved part is ...
