     25 # This workloads emulates a video server. It has two filesets, one of videos
     26 # being actively served, and one of videos availabe but currently inactive
     27 # (passive). However, one thread, vidwriter, is writing new videos to replace
     28 # no longer viewed videos in the passive set. Meanwhile $nthreads threads are
     29 # serving up videos from the activevids fileset. If the desired rate is R mb/s,
     30 # and $nthreads is set to T, then set the $srvbwrate to R * T to get the
     31 # desired rate per video stream. The video replacement rate of one video
     32 # file per replacement interval, is set by $repintval which defaults to
     33 # 10 seconds. Thus the write bandwidth will be set as $filesize/$repintval.
