The invention discloses an objectification parallel computing method and system for information system performance improvement. The method is suitable for a cluster environment, and computers in a cluster are divided into object servers, object management servers and client agents according to functions. The method mainly comprises the following steps that object-oriented modeling is carried out, power service data are abstracted into data objects according to rules, and task information is abstracted into task objects; distributed cache is carried out on the objects, and the data are cached in the object pools of a plurality of object servers in a distributed mode according to an object model; object indexes are created, all object pool information is collected by the object management servers, and the indexes are created according to a logical relationship; parallel computing is carried out on tasks, the task objects are divided into a plurality of stages of subtasks according to certain rules, the subtasks are executed in parallel, and finally a result is returned to the task objects. On the basis of the method, the objectification parallel computing system for the information performance improvement is provided. The problem that the real-time computing performance of an information system is poor can be solved.
