Introduction
In the design and use of a data processing system, execution speed is an important property. Mainly due to the nature of the software used in the system
Efficiency. Measurement software execution speed, efficiency and impact of software, is most concerned about.
To measure the impact of software in terms of time-varying behavior of a data processing system, it is necessary to measure the time-varying behavior of the entire system. base
This standard proposed measurement procedures and calculation software definable time efficiency value.
Time-varying behavior can be repeated estimate is very important. In experiments with a real user is not possible, a reason is not real user
As may perform like a computer under the premise of no deviation of repeated operations, the other reason is that when the work or task flow from many users
When, if the real user to perform such experiments, it takes a very high price. Thus, the need to use the test simulator, the simulation
Via an auxiliary data processing system to simulate multi-user operation.
This means performance measurement and rating accordance with this standard requires the use of tools. The tool should be in accordance with the requirements of this standard specification
Run the simulator. It should prove actual use of simulators to meet these specifications.
All relevant experimental details are recorded in the log file the user simulator through. By the log file, calculate the change line description
A value (such as response time and throughput). Based on these performance values, calculated software efficiency rating value.
Not all property values \u200b\u200bneed to be measured and ratings. For example, for a system with a simple software load, only a few
Interactive tasks, or only a small batch execution requirements, only need to define a part of the performance indicators and their values. The method is also suitable for measuring and
Rating large, complex computer-based software system (CBSS), CBSS handle complex work by a number of different user-generated flow
Or task flow. Definition necessary to include a number of mathematical terms, the purpose of computing performance and value rating value, operation and calibration measurement step rating
Sudden correctness, and to determine the value and performance ratings of significance to obtain precise mathematical basis (statistical).
Performance measurement results by the calculated value, including the value of throughput and execution time. The end result CBSS performance evaluation by rating
Value constituted. Rating value can be obtained by comparing the user needs performance values. Further, if necessary, by a reference with CBSS (e.g.,
Different versions have the same hardware configuration, but with the same functionality of the application) performance compared to the value, you can treat the measured performance value CBSS
Rating.
The rating result is a set of values, each value or greater than 1, or less than 1 or equal to 1, respectively, the performance is better than, worse than, equal to a given
Demand justice (or another as a reference test system characteristics). The final rating for each set of values \u200b\u200bto assess workload defined separately
Task type.
Appendix E and Appendix F contains special software and data, because they can not print, so the standard is not provided. In two appendices are
It provides a brief overview.
Information technology, computer-based
Software System Performance Measurement and rating
1 Scope
This standard defines the computer-based software system (CBSS) user-oriented performance and how to measure ratings. From the user (for example, each
Different kinds of user terminals, or data processing center operations and business users) point of view, CBSS is a data processing system.
CBSS includes all hardware and software (system software and application software), which are required for the implementation of user data processing functions to be
Ask, or may affect the time to change the behavior of the CBSS.
This standard applies to all time-bound part of the test system or systems. Similarly, the network may be an integral part of a system
Points, or may become a test subject. The method as defined in this standard is not limited to the classic image of a batch or terminal - host systems and other special cases, for example,
For example, including client - server system or for broad understanding of the "mission" real-time systems defined. But it takes for the test environment to
Say, practical test will be limited.
This standard provides the key indicators for the performance of the terms of users, as well as measuring and rating the performance values \u200b\u200bof the method. Of prescribed
Emergy describes the user command performance values \u200b\u200b(task) execution speed, that follows the "Trinity".
---execution time;
--- Throughput;
--- Timeliness.
User command, hereinafter referred to task, in the internal structure can be very simple or very complex. A task may be a job, things
Services, processes, or a more complex structure, but have a defined start time and end time needed evaluators. Performance reviews,
In addition to the individual response time, it can also refer to a business transaction completion time, the use of this standard to measure the behavior of the system becomes.
Rating according to user needs to complete, or by two or more of the measured system (type or version) compared to complete.
For measuring the internal value, for example.
--- Use value;
--- The average rate of instruction;
--- Path length;
--- Cache hit rate;
--- Queuing time;
---service hours.
Deliberately not give advice, because the definition of internal value depends on the hardware and software architecture of the measurement system. In contrast, the standard definition of this
The user-oriented performance values \u200b\u200bare independent of the architecture. Internal performance definition of values, independent of the definition of user-oriented performance values. except
External value of the user-oriented performance, these internal performance values \u200b\u200bcan be used, it can also be measured. The term also generates user-oriented value efficiency can
Freely defined. In addition, the standard for how to build a data processing system is stable, reproducible operating state gives guidance, these can be
The current state can be used to measure the value of other properties, e.g., the above-mentioned internal value.
This standard focuses on.
---application;
---system software;
--- Turnkey system (ie by the application software, system software and hardware designed for this purpose consisting of systems);
--- General data processing system.
This standard specifies the relevant simulation [so-called remote terminal emulator through technical system (RTE)] user interaction with the data processing system
