Wow! Thanks. That'l teach me to use a non-default tech without researching it.
Over the years, my MythTV box had gotten inexplicably slow with lots of disk access for many operations like starting playback of a recorded video. With the advice here, I measured 98.6% fragmentation. A few sample files I checked that were 1-6GB captured MPEG-2 videos were stored on over 30,000 extents!
After 2 nights of de-fragmenting, I'm down to 17% fragmented and startup time of playing a video is noticeably faster with less hard drive activity.
