That’s because we let customers customise the virtual CPU core to optimise performance for different applications. Although our physical CPU cores are usually 2.5GHz each, customers can vary that. For example, if you have a server of size 10GHz, you can set that to have 10 virtual cores of 1GHz each or 4 virtual cores of 2.5GHz or anything in between. So if you have an application that needs more CPU threads but less performance per core, you’d set it to have ten cores. In this way you can boost performance without incurring additional resource costs. Don’t worry, the default is set to auto so it’s not a feature you need to deal with unless you want to.
