Methods and systems for enhanced computer performance improve software application execution in a computer system using, for example, a symmetrical multi-processing operating system including OS kernel services in kernel space of main memory, by using groups of related applications isolated areas in user space, such as containers, and using a reduced set of application group specific set of resource management services stored with each application group in user space, rather than the OS kernel facilities in kernel space, to manage shared resources during execution of an application, process or thread from that group. The reduced sets of resource management services may be optimized for the group stored therewith. Execution of each group may be exclusive to a different core of a multi-core processor and multiple groups may therefore execute separately and simultaneously on the different cores.
