+.BI replay_time_scale \fR=\fPint
+When replaying I/O with \fBread_iolog\fR, fio will honor the original timing
+in the trace. With this option, it's possible to scale the time. It's a
+percentage option, if set to 50 it means run at 50% the original IO rate in
+the trace. If set to 200, run at twice the original IO rate. Defaults to 100.
