TSS/360: a time-shared operating system

Alexander Stafford Lett; William L. Konigsford

Experience with TSS/360 design, development, and application has been varied and interesting. For example, as we began putting the initial system together, significant performance problems were observed that had not been predicted by the earlier simulation efforts. These problems had not been anticipated because the paging characteristics assumed in the model development were significantly better than the actual system characteristics.
