  7. .SH DESCRIPTION
  8. .B loop_o
  9. reports the
  10. .IR for ()
  11. loop overhead associated with measuring timing intervals.
  12. This is critical mostly for experiments which measure very
  13. fast operations, such as memory loads, and which haven't
  14. been designed to minimize the loop overhead effects by
  15. some form of manual loop unrolling.
