How Do I Determine the Number of Cores in My Computer?
Pro licensed engines are limited to the number of servers and cores in those servers. Modern computers have multi-core processors containing two or more independent processing units called cores. Through a technique called hyper-threading, physical cores appear to be multiple logical processors or virtual cores to the operating system.
Flex licensed engines are unlimited on the number of servers and cores since they are limited by number of pages. Flex licensed engines are meant to be used in auto scaled and auto managed environments.
