Potential for cost savings
A variation that has a high potential for cost savings, is the licensing on the basis of so-called PVU metric (Processor Value Unit). Here the cost of the software are determined not on the number of users or installations, but on the performance of the processors. After a points table each processor model is depending on the performance and configuration associated with a certain number of points, which forms its PVU value. This value is then multiplied by the number of available cores. From these figures the required number of PVU licenses that will be charged as a basis for calculating the price to be licensed Software.
