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.
Useful readings§
This class provides the following generally usable readings (in alphabetical order):
cpu
The total amount of CPU time (in microseconds), essentially the sum of cpu-user
and cpu-sys
.
cpu-sys
The number of microseconds of CPU used by the system.
cpu-user
The number of microseconds of CPU used by the user program.
cpus
The number of CPU's active, essentially cpu
divided by wallclock
.
max-rss
The maximum resident set size (in KiB).
util%
Percentage of CPU utilization, essentially 100 * cpus
/ number of CPU cores.
wallclock
The time the program has been executing (in microseconds).
Less useful readings§
The following readings may or may not contain sensible information, mostly depending on hardware and OS being used. Please check your local getrusage
