  • A utility function that returns an estimate of the number of logical cores on the system.

    This value can be used to help provide an estimate of how many threads to use with the MultiThreadedEventLoopGroup. The exact ratio between this number and the number of threads to use is a matter for the programmer, and can be determined based on the specific execution behaviour of the program.

    Declaration

    Swift

    public static var coreCount: Int { get }

    Return Value

    The logical core count on the system.
