Abstract: An adaptive throttling system for minimizing the impact of non-producti on work on production work in a computer system. The adaptive throttling system throttles production work and non-production work to optimize production. Th e adaptive throttling system allows system administrators to specify a quantified limit on the performance impact of non-production or utility work on production work. The throttling rate of the utility is then automatically determined by a supervisory agent, so that the utilities' impact is kept within the specifie d limit. The adaptive throttling system adapts dynamically to changes in workloads so as to ensure that valuable system resources are well utilized and utility work is not delayed unnecessarily.
