Problems solved by technology
However, in the optimization process, these methods do not fully consider the use times and order uncertainty of each rule in the rule combination scenario, so that they can only search for a relatively small performance improvement space, and it is often difficult to obtain the optimal performance improvement.

The invention relates to a rule-based software architecture layer performance optimizing model building method. The rule-based software architecture layer performance optimizing model building method includes that numbering n performance improvement rules in sequence according to 1 to n; defining a rule number sequence FORMULA (shown in the description) to express a performance improvement scheme, and using ui to express the maximum occurrence number of the rule i in X; respectively defining the length l of the X, the value range of each element xk in the X and the occurrence number hi(X) of the rule i in the X through the formula (1), formula (2) and formula (3), FORMULAS (shown in the description); defining a function g(X) to express a target function corresponding to the performance optimization FORMULA (shown in the description); building the software architecture layer performance optimizing model which enables the g(X) to be the maximum through solving X based on meeting conditions of the formulas (1), (2) and (3). The software architecture layer performance optimizing model built by the method is capable of lowering the software architecture layer performance optimizing cost and improving the optimizing quality.
Description
technical field [0001] The invention relates to the technical field of software performance optimization, in particular to a modeling method of a rule-based software architecture layer performance optimization model. Background technique [0002] The performance of software is an important attribute to measure the quality of software system, and the quality of performance has become the key factor for the success or failure of the system. Performance optimization in the software architecture (Software Architecture, abbreviated as SA) design stage can detect performance problems such as high resource usage, long response time, and low throughput as early as possible, and alleviate or eliminate them through corresponding design improvements These problems, so as to obtain the SA design scheme that meets the performance requirements, and then achieve the purpose of performance optimization in the early stage of the software life cycle. Performance optimization based on SA can ...
