Performance Tools

The task of running a benchmark originally was limited to estimating the time consuming process of implementing a program (usually measured in thousands or millions of operations per second).
Over time, improvements in compilers and the wide variety of architectures and situations made this technique in any specialty It can also be a “benchmark software”, ie comparing performance against other software or part thereof, for example, compare different queries to a database to know the fastest or pieces of code directly.
A benchmark is a set of procedures (software) to evaluate the performance of a computer.There are four general categories of comparison tests:
• Evidence-based applications (application-based) and the timed runs.
• Testing playback (playback test), which use system calls for application-specific activities (eg graphics calls or use the disc) and run in isolation.
• Proof synthetic (synthetic test), which links the implementation activities in specific subsystems.
• Proof of inspection (inspection tests), which does not attempt to mimic the activity of the application, but that runs directly on the specific subsystems.
Why consider the performance?
• Judging the performance of a system when you are making purchase decisions is critical in order to delay obsolescence and protect your investment.
• The Pentium (R) offer longer shelf life.
• You want the most in the purchase of your system. Part of this is to ensure that the system lets you choose what you want during the lifetime of the system. This means that not only will manage the software today but has the recursosnecesarios to run more complex programs of tomorrow.
• As shown in the diagram above, for any given point in time is available a range of processors – those that offer the best performance possible and those that offer a minimum level of performance.The arrows indicate that buying the best performance you get a longer life.
• It is important to evaluate a number of aspects of their performance when making purchasing decisions.
Factors in the performance of a computer
•The overall performance can you get your PC depends on how each of its components work together to accomplish a task. The effect of each individual component may vary depending on how much is engaged in executing a particular application. As shown below, 54% of the system performance depends on your processor, or CPU, when running typical Windows * applications. Other components such as memory, video and disc also play a role. A “weak link” in the system can significantly reduce the speed and response time that you experience.
The percentages represent the use of components that are running Windows * Typical applications
Therefore, when choosing a system, you should start looking for which is the processor that offers the best performance for your software, a preciorazonable. Then can you begin to analyze the other system components to ensure they enjoy all the benefits of processor power.
