Tuning utilization and heap memory size for real-time garbage collection

A computer program product comprising:

• a tangible storage medium readable by a processor and storing instructions for execution by the processor to perform a method comprising:
• providing a user interface to a user for assisting the user with identifying parameters for starting an application that utilizes real-time garbage collection (GC), the parameters including a fixed heap size and a GC central processing unit (CPU) utilization;
• responsive to receiving a request from the user, providing the user with options for profiling the application, the options including targeting the GC CPU utilization to meet real-time requirements, targeting the heap size to meet the real-time requirements, and targeting a balance between the GC CPU utilization and the heap size to meet the real-time requirements;
• responsive to detecting a selection of an option by the user, profiling the application according to the option selected, the profiling including executing the application;
• and
• presenting the user with results of the profiling, the presenting via the user interface and the results including values for the parameters.
