cjolivier01 commented on issue #9744: Performance regression when 
OMP_NUM_THREADS environment variable is not set

   i don?t set the environment variable. I doubt it would
   work even if i did, from within the code. So there?s nothing I can do,
   then, right? User would need to set?
   
   I recall dumping the default behavior of KMP and i remember it showing that
   the OMP threads were indeed staggered as in your picture.  I?ll check again.
