Resolving application multitasking degradation

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computing device to cause the computing device to:

• run a plurality of active applications on the computing device;
• detect a change in application focus on the computing device by continuously monitoring the computing device for the change in application focus;
• assign priorities to at least some of the plurality of active applications, resulting in a first priority application and a second priority application having different levels of priority;
• monitor performance parameters of each of the first priority application and the second priority application;
• determine that one or more of the monitored performance parameters of the first priority application has fallen below a performance threshold value of an associated key performance indicator (KPI), wherein the determination indicates a degradation in performance of the first priority application;
• and
• modify an allocation of shared computing device resources to address the degradation in performance of the first priority application, wherein the allocation of the shared computing device resources is modified based on the priority level of the first priority application.

A system comprising:

• a CPU, a computer readable memory and a computer readable storage medium associated with the computing device;
• program instructions to run a plurality of active applications on the computing device;
• program instructions to detect a change in application focus on the computing device by continuously monitoring the computing device for the change in application focus;
• program instructions to assign priorities to at least some of the plurality of active applications, resulting in a first priority application and a second priority application having different levels of priority;
• program instructions to monitor performance parameters of each of the first priority application and the second priority application;
• program instructions to determine that one or more of the monitored performance parameters of the first priority application has fallen below a performance threshold value of an associated one of key performance indicators (KPIs), wherein the determination indicates a degradation in performance the first priority application;
• and
• program instructions to modify an allocation of shared computing device resources to address the degradation in performance of the first priority application, wherein the allocation of the shared computing device resources is modified based on a priority level of the first priority application, and
• wherein the program instructions are stored on the computer readable storage medium for execution by the CPU via the computer readable memory.
