Minimizing costs with no performance requirements usually involves putting together a machine with leftover parts (that old 386SX-16 box lying around in the garage will do fine) and does not require benchmarks, and maximizing performance with no cost ceiling is not a realistic situation (unless one is willing to put a Cray box in his/her living room - the leather-covered power supplies around it look nice, don't they ?).īenchmarking per se is senseless, a waste of time and money it is only meaningful as part of a decision process, i.e. One will have to examine, compare and/or produce benchmarks. How do I obtain the best performance/cost ratio (within a given budget or given performance requirements)?.How do I minimize costs for a required minimum performance level ?.How do I maximize performance within a given budget ?.In other words, when confronted with the following questions: Very often the results are not what one would expect, and subject to interpretation (which actually may be the most important part of a benchmarking procedure).įinally, benchmarking deals with facts and figures, not opinion or approximation.Īpart from the reasons pointed out in the BogoMips Mini-HOWTO (section 7, paragraph 2), one occasionally is confronted with a limited budget and/or minimum performance requirements while putting together a Linux box. It does not involve user-friendliness, aesthetic or ergonomic considerations or any other subjective judgment.īenchmarking is a tedious, repetitive task, and takes attention to details. "What we cannot speak about we must pass over in silence." Ludwig Wittgenstein (1889-1951), Austrian philosopherīenchmarking means measuring the speed with which a computer system will execute a computing task, in a way that will allow comparison between different hard/software combinations.

The Linux Benchmarking HOWTO discusses some issues associated with the benchmarking of Linux systems and presents a basic benchmarking toolkit, as well as an associated form, which enable one to produce significant benchmarking information in a couple of hours.
