Note: This class is a Rakudo-specific feature and not standard Raku.
Objects of this class are generally not created by themselves, but rather through making a snapshot.
This class provides the following generally usable readings (in alphabetical order):
The total amount of CPU time (in microseconds), essentially the sum of
The number of microseconds of CPU used by the system.
The number of microseconds of CPU used by the user program.
The number of CPU's active, essentially
cpu divided by
The maximum resident set size (in KiB).
Percentage of CPU utilization, essentially 100 *
cpus / number of CPU cores.
The time the program has been executing (in microseconds).
The following readings may or may not contain sensible information, mostly depending on hardware and OS being used. Please check your local
