AIX base perf commands (ps, svmon,...)
ps command
working with percent
- pcpu Indicates the ratio of CPU time used to CPU time available
- pmem Indicates the percentage of real memory used by this process

- vsz Indicates, as a decimal integer, the size in kilobytes of the core image of the process
- ruser Indicates the real user ID of the process
