The present disclosure relates to a method, device and computer program product for executing a job in an application system. Here, the application system comprises a first processing device and a second processing device, and a first response speed of the first processing device being lower than a second response speed of the second processing device. In a method, a job request is received from a user of the application system, the job request specifying that the job is to be executed in the application system; a job type of the job is determined, the job type describing a requirement of the user on a response speed for executing the job; a target processing device is selected from the first processing device and the second processing device in accordance with determining that the job type relates to a high response speed; and the job is assigned to the selected target processing device, so that the job is executed by the target processing device. By means of the above method, a processing device for processing a job is selected based on the type of the job, and further processing devices in the application system may be dispatched more effectively. Furthermore, there is provided a corresponding device and computer program product.
