Abstract : The report attempts to answer some of the questions concerning the advantages and disadvantages of time-sharing. To accomplish this, the general problem of evaluating computer system performance is first addressed. General system characteristics are specified that include the computer and its operating system, and users and their jobs. The main emphasis is placed upon the operating system; the effects of having different computers, users, or jobs are treated as parameters. The most important evaluation criterion is considered to be cost, which includes both user cost and computer system cost. Quantitative models are developed that describe computer center users, the programs they run, and the different operating systems they might use.
