1. A performance evaluation device for measuring performance of an information processing system providing a service based on an inputted measurement condition, comprising: a condition input screen via which information relevant to said measurement condition is to be inputted, wherein said condition input screen is divided into a portion relevant to a first information processing apparatus group consisting of at least one information processing apparatus and providing said service, a portion relevant to a second information processing apparatus group consisting of at least one information processing apparatus and receiving said service, and a portion relevant to said service, this common form is used as said condition input screen irrespective of said service, and a plurality of set values are allowed to be inputted for one item in said measurement condition on said condition input screen, and wherein set values of different items in said measurement condition, which are inputted via said condition input screen, are arbitrarily combined to automatically generate performance test data, each of the performance test data consisting of one set of a set value group consisting of the set values of the different items in said measurement condition, and said information processing system is controlled to execute a performance measurement test based on the generated performance test data.
