Responsiveness analysis device

Provided is a responsiveness analysis device capable of efficiently confirming the responsiveness of an API. A responsiveness analysis device is provided with: an execution history acquisition unit that acquires history information relating to an API; a first determination unit that determines an execution cycle and a processing time of the API corresponding to a newly added application; a second determination unit that determines, on the basis of the history information acquired by the execution history acquisition unit, an execution start time and a processing time of the API corresponding to an existing application program; and a responsiveness analysis unit that analyzes the responsiveness of the API on the basis of the execution cycle and processing time of the API corresponding to the newly added application, and the execution start time and processing time of the API corresponding to the existing application. 本发明提供一种能够高效地确认API的响应性的响应性解析装置。响应性解析装置具备：执行履历取得部，其取得与API相关的履历信息；第一决定部，其决定与新追加的应用程序对应的所述API的执行周期
