標題[問題] 關於作業系統 - CPU Scheduling
時間Sat Feb 13 02:04:27 2010
這是一題資格考的題目,找不太到答案,想知道大家的想法
As a system designer, how would you know when you have chosen the
best time quantum? What factors would make this time quantum best
from the user's point of view? What factors would make this time
quantum best from the system's point of view?
個人想法是:
從使用者觀點來考量,response time為優先
從系統觀點來考量則是希望throughput越大越好
希望藉由大家想法與討論精鍊出合理的答案
先謝謝了..
