Towards More Effective Utilization of Computer Systems

Globally, vast infrastructures of Information Technology (IT) equipment are deployed. Much of this infrastructure is under utilized to ensure acceptable response times. This results in less than ideal use of the capital investment used to purchase the IT equipment. To improve the sustain-ability of IT, the authors focus on increasing the effective utilization of computer systems. Their results show that computer systems running delay-sensitive (e.g., Web) workloads can be more effectively utilized while still maintaining adequate (e.g., mean or upper percentile) response times.
