Multi-component link performance positioning method and device

The invention relates to a multi-component link performance positioning method and device, and belongs to the technical field of software development. Coarse-grained parameter definition can be carried out on a plurality of single components through grid search, and the general direction of parameter optimization is determined. Then, optimization is carried out on the fine-grained parameter level by using parallel random walk, and sub-optimal parameters close to the optimal parameters can be accurately obtained; and finally, the effects of saving machine resources and meeting service requirements are achieved by adopting a search algorithm in a link parameter search stage. According to the method and the device provided by the invention, the pressure measurement process data is reserved, and a two-stage positioning mode is adopted, so that a pressed link is ensured to stably operate in a system safety margin while meeting a high-performance requirement. 本申请涉及一种多组件链路性能定位方法及装置，属于软件开发技术领域。通过网格搜索可以对多个单一组件进行粗粒度参数界
