  • Patent number: 9489235
    Abstract: A processing method has been claimed for reducing the average wait time of requests in a queue in a system environment where garbage collection may occur. In the method, a computer system treats as a unit each request in a queue and a completion time of garbage collection that may occur at the time of processing the request, and processes requests preferentially and systematically in ascending order of the processing times of the units including the garbage collection times, thereby, reducing the average wait time of the requests. While, the computer system managing the queue knows the remaining amount of heap just before processing a certain request, the computer system statistically calculates in advance the amounts of heap to be consumed on a request type basis and holds the values.
