even if the file(s) are completely read or written. It will simply loop over
the same workload as many times as the :option:`runtime` allows.
-.. option:: startdelay=irange
+.. option:: startdelay=irange(time)
Delay start of job for the specified number of seconds. Supports all time
suffixes to allow specification of hours, minutes, seconds and milliseconds
I/O rate
~~~~~~~~
-.. option:: thinktime=int
+.. option:: thinktime=time
Stall the job x microseconds after an I/O has completed before issuing the
next. May be used to simulate processing being done by an application. See
:option:`thinktime_blocks` and :option:`thinktime_spin`.
-.. option:: thinktime_spin=int
+.. option:: thinktime_spin=time
Only valid if :option:`thinktime` is set - pretend to spend CPU time doing
something with the data received, before falling back to sleeping for the
I/O latency
~~~~~~~~~~~
-.. option:: latency_target=int
+.. option:: latency_target=time
If set, fio will attempt to find the max performance point that the given
workload will run at while maintaining a latency below this target. The
values is given in microseconds. See :option:`latency_window` and
:option:`latency_percentile`.
-.. option:: latency_window=int
+.. option:: latency_window=time
Used with :option:`latency_target` to specify the sample window that the job
is run at varying queue depths to test the performance. The value is given
defaults to 100.0, meaning that all IOs must be equal or below to the value
set by :option:`latency_target`.
-.. option:: max_latency=int
+.. option:: max_latency=time
If set, fio will exit the job if it exceeds this maximum latency. It will
exit with an ETIME error.
