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:
Computer manufacturers frequently bring out new models, often with higher performance. Software costs can be quite high, so in some cases the simplest and cheapest way of getting higher performance might be to just buy a faster computer, provided it is compatible with an existing computer.
In contrast, one may need to perform less work to make part A perform twice as fast. This will make the computation much faster than by optimizing part B, even though part B's speedup is greater in terms of the ratio, (5 times versus 2 times). For example, with a serial program in two parts A and B for which T A = 3 s and T B = 1 s,
If your computer is experiencing one or more of these issues, you should run a detailed health check. This will help you uncover the root cause, create a repair strategy, and take immediate action.
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.
One possible reason for super-linear speedup in low-level computations is the cache effect resulting from the different memory hierarchies of a modern computer: in parallel computing, not only do the numbers of processors change, but so does the size of accumulated caches from different processors.
