====== 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
