| Abstract: | Summary The behaviour of the paging drum or disc has a significant impact on the performance of multiprogrammed, paging systems. A study is made of such devices using the three tools of performance evaluation: an analytical model, a simulation model and empirical measurements. The models extend previous studies by including non-exponential arrival times and a comparison is made between the proposed analytical model and standard models using Poisson arrivals. |
