Metrics
are criteria to compare the performances of a system. In general, the metrics are related to speed, accuracy, reliability and availability of services. The basic characteristic of a computer system that we typically need to measure are:
Since many performance metrics turn out to be misleading, people have designed benchmarks I Example: SPEC Benchmark I Integer benchmark I Floating point benchmark I These benchmarks are typically a collection of several codes that come from “real-world software†I The question “what is a good benchmark†is di
ffi
cult I A benchmark is representative of a given workload. If the benchmarks do not correspond to what you’ll do with the computer, then the benchmark results are not relevant to you
I other typical benchmarks I Livermore loops, NAS kernels, LINPACK . . . I SPEC SFS, SPEC Web . . .
A Monitor
is a tool to observe the activities on a system. In general, a monitor:
1 makes measurements on the system (Observation)
2 collect performance statistics (Collection),
3 analyses the data (Analysis),
4 displays results (Presentation).
Observation
is commonly performed with three mechanisms:
ff
er an API to incorporate such hooks or exports the values of internal counters.

Probing Making “feeler†requests on the system to sense its current performance. Some activities can be observed by only one of the three mechanisms.
Gigahertz is equal to 1,000 megahertz and is used in measuring speed of computer processing.

PERFORMANCE, SPEED and RELIABILITY
the computer is what runs the car and all the engine functions, you can change the functions of the engine to get more power by buying a performance programmer and downloading the program into the cars computer. theres your answer :)
The parameters for measuring the performance of any computer system are, in very basic terms, the amount of giga-updates that can be performed per second. This number can then be used to calculate other factors of performance.

Most typically, Benchmarking programs are used. These are programs which simulate normal use under stressful conditions and guage the performance of the computer for comparison with other systems.
The theory of Queing is a complex area of engineering that can be called waiting lines. It is a tool for studying several performance parameters of computer systems.
Quad-Core chips have 4 processor cores. The base price is 150 dollars. It offers excellent computer performance and power efficiency. It is designed to perform highly threaded programs.

If you replace your engine with one that is not exactly the same year or displacement you are asking for problems. The manufacturers are constantly improving performance and efficiency by changing parameters in the computer controlled engine management systems. It will be different for every year and engine size, thus using the computer from say a '91 3.4L to control a '91 3.8L could cause a rich condition or some other issue, timing or high idle, etc.
