In computing, computer performance is the amount of useful work accomplished by a computer system. Outside 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:Short response time for a given piece of work. High throughput. Low utilization of computing resources. Fast data compression and decompression. High availability of the computing system or application. High bandwidth. Short data transmission time.
