trickplay scan take so long ?

[bitmap]

I know I'm butting in, but figured I would share where I'm at since I have been working through this as others have stated long run times.

The process kept stopping and restarting for a few reasons, so I removed the scheduled task, ran the task, and have been watching it since. I am currently at 92.8% after almost exactly 228 hours of trickplay file generation. My config dir is now 76 GB, up from ~30 GB before trickplay file generation (I didn't take an initial measurement before files started generating). I can estimate by saying that /config/data/metadata (where trickplay files live) is 48 GB, however, other metadata lives there and contributes to this total. My /config/data dir accounts for 70/76 GB of my install directory.

I also have a sneaking suspicion I need to clean up a bit in there, but I'm not keen on touching anything I don't know the purpose of as of yet...
