The NavigatorConcurrentHardware mixin adds to the Navigator interface features which allow Web content to determine how many logical processors the user has available, in order to let content and Web apps optimize their operations to best take advantage of the user's CPU.

Nota: Esta característica está disponible en Web Workers.

The number of logical processor cores is a way to measure the number of threads which can effectively be run at once without them having to share CPUs. Modern computers have multiple physical cores in their CPU (two or four cores is typical), but each physical core is also usually able to run more than one thread at a time using advanced scheduling techniques. So a four-core CPU may return 8. The browser may, however, choose to reduce the number in order to represent more accurately the number of Workers that can run at once
