func Counts(logical bool) (int, error)
Counts returns the number of physical or logical cores in the system
func CountsWithContext(ctx context.Context, logical bool) (int, error)
func Percent(interval time.Duration, percpu bool) ([]float64, error)
Percent calculates the percentage of cpu used either per CPU or combined. If an interval of 0 is given it will compare the current cpu times against the last call. Returns one value per cpu, or a single value if percpu is set to false.

func Info() ([]InfoStat, error)
CPUInfo on linux will return 1 item per physical thread.
CPUs have three levels of counting: sockets, cores, threads. Cores with HyperThreading count as having 2 threads per core. Sockets often come with many physical CPU cores. For example a single socket board with two cores each with HT will return 4 CPUInfoStat structs on Linux and the "Cores" field set to 1.

TimesStat contains the amounts of time the CPU has spent performing different kinds of work. Time units are in seconds. It is based on linux /proc/stat file.
