How to prevent /proc/<pid>/status from running slow on AIX ?

Hi AIX experts,

do you have any idea how to prevent /proc/<pid>/status from running
slow on AIX (compared to times() and getrusage())?

Please have a look at the attached program which describes and
demonstrates the problem in full detail.

I'd need a workaround for this problem for the AIX port of the new
ProcessHandle implementation which came as part of JEP 102.

Thank you and best regards,
