2.1. CPU performance
To monitoring and tuning of CPU performance, it is important to know about process and scheduling. This section gives an overview of the process, thread, and scheduling which are closely related to the performance of CPU.
2.1.1. Processes and threads
An understanding of the way processes and threads operate within the AIX environment is required to successfully monitor and tune AIX for peak CPU throughput. The following defines the differences between threads and processes:
| Processes | A process is an activity within the system that is started with a command, a shell script, or another process. |
| Threads | A thread is an independent flow of control that operates within the same address space as other independent flows of controls ... |
