SystemInfo.processorCount

Description

Number of processors present (Read Only).

This is number of "logical processors" as reported by the operating system, also commonly called as "number of hardware threads". Note that some CPUs have different amount of "physical cores" and "logical cores" (for example many Intel CPUs have 4 physical cores and 8 logical cores in so called "hyper threaded" fashion). This function reports the latter.
