-time process), a process with a high priority usually gets a longer time slice and more compute time than a low-priority process, but this does not mean that low-priority processes are completely ignored (starved). The advantage of this algorithm is to increase the scalability of the Linux kernel for enterprise-class environments with a large number of threads and processes and multi-processors. The new CPU Scheduler for O (1) was designed for memory

4.1Process Performance Statistics4.1.1.Kernel TimeVsUser TimeThe most basic partitioning of an application's time is the kernel time and user time. Kernel time is spent on the Linux kernel, while user time is spent on the application or library code. Linux has tools, such as time and PS, that can (roughly) indicate whether the application spends its hours on the
