Cabanga ngesistimu ye-CPU eyodwa ongaqala ngayo: Isikhathi se-CFS sisika i-CPU phakathi kwemicu esebenzayo. Kunesikhawu sesikhathi esimisiwe lapho uchungechunge ngalunye ohlelweni kufanele lusebenze okungenani kanye.

How does Linux scheduler work?

Umhleli ukhetha umsebenzi olandelayo ozokwenziwa, futhi ugcina ukuhleleka, okufanele zonke izinqubo ohlelweni ziqhutshwe ngawo, nazo.
