AppleTV 2 (black) Slow movie library load

Between those it's:

1. Doing a query to retrieve streamdetail information for each item in the list.
2. Hitting the filesystem for art for each item in the list.

If either are over mysql then it'll most likely be slow. You should be able to trace what's happening on your network to confirm this.

Changing to local thumbnail storage helped a little bit with my setup, but obviously this isn't as convenient when using shared database, as you need to set up another process to copy the thumbnails around to devices.

So a part of the delay is retrieving stream details? Can this be improved by scraping details for all media and storing it in the individual nfo files? (Most of my media already is), or will XBMC still retrieve stream details from the media files on access?

It's retrieving it out of the database, not out of your files, so no, having it in the nfo file won't make any difference here.

Copy that. Thanks for the info.

Great, thanks for the info. The library is stored on MySQL, so I'll stick some tracing on and see what it's doing.

Also, the thumbnails are being read over the network (I've got path substitution set up) and a quick test of this showed that it did help a bit.

So I went off and looked at the network traffic just so that I could understand what was going on. I was all set to write up my findings but went looking around first and saw this:

where it has all been documented pretty thoroughly. I figure there's not much point uploading my stats although I can if anyone is interested.

Nice find. Will have to check if JMarshall has pushed those changes to master yet.

The thumbs are off-thread now. Stream details are still on-thread.

Nice. I guess I'll get to test it out when ATV2 builds start up again.

Stream details on the to-do list?

Yes.
