328 psb_period Allows the frequency of PSB packets to be specified.
333 Support for psb_period is indicated by:
347 The psb_period value is converted to the approximate number of

361 of 3 (i.e. psb_period=3) or the nearest lower value that is
562 The calculation used for that is: if sample_size <= psb_period + 256 display the
563 warning. When sampling is used, psb_period defaults to 0 (2KiB).
