CPU scheduler is a very important key concept in operating system which affects scheduling objectives and criteria. Choosing or modifying scheduling policy for running threads depends on predefined and specific objectives and criteria. In this paper, the authors investigate the effectiveness of Thread Weight Readjustment Scheduler (TWRS) for multithreaded processes in multitasking operating systems from the view point of throughput. TWRS is a proportional share CPU scheduler designed for scheduling multithreaded processes. In this paper, they make change kernel performance significantly by modifying just few key parameters.
