A Platform Independent Tool for Evaluating Performanceof Computing Equipment for a Computer Laboratory

摘要

Designing computing equipment for a computer laboratory is notrneasy. In a class in a computer laboratory, it is not unusual that allrnstudents do the same thing simultaneously. Tremendous traffic isrnon the network and heavy load is on the file server or the webrnserver at that time. In order to design the equipment, it is useful ifrnwe can have performance data which is acquired in a real class.rnAnd it is more useful if we can compare the performance data ofrnvarious kind of equipment which is acquired by doing the samernoperations in a real class. In order to acquire such kind of data, wernare developing a benchmark test tool for distributed systems. Thisrntool records real operations by users on computing equipment andrnit acquires its performance data. The tool can replay the samernoperations on different computing equipment. The tool can alsornlet every computer doing the same thing simultaneously. In orderrnto compare the performance data of various kind of computingrnequipment, this tool is in Java. So it is platform independent. Wernshow the structure of the tool and the experiment of the usage ofrnthe tool.
