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.
