This technology relates to assigning a task to a current task queue based on one or more matching category when the new task is received within an application for execution. Availability of one or more existing idle threads within one or more thread groups required for the execution of the received task determined based on one or more utilization parameters, where each of the thread groups is associated with one or more task queues and where the current task queue is one of the task queues. One or more new threads are created to allocate for execution of the task when the existing idle threads are determined to be unavailable in the thread groups within the application. Next, the created new threads are allocated to the task when the existing idle threads are determined to be unavailable. The task is executed using the allocated new threads.
