Computer retailers describe the performance of their machines in terms of CPU Speed (in MHz or GHz). This refers to the number of instructions the Central Proccessing Unit (CPU) can perform each second (in millions or billions respectively). However this is only one of a number of factors that impact on the performance of a machine. |

Since cost is usually constant, the variables usually consist of latency, throughput, convenience, storage capacity and input-output. The general scheme of optimization is to budget different parts of the computer system. In a balanced computer system, the data rate will be constant for all parts of the system, and cost will be allocated proportionally to assure this. The enact forms of the trade-offs depend on whether the computer system is being optimized to minimize latency or maximize throughput. |
