Comment(by sphery <mtdean at thirdcontact.com>):
The attached patch, mythtv-find_file_for_preview_gen.patch , modifies the
Storage Group changes committed in [15029] based on the suggestion from
Chris Pinkham at http://www.gossamer-
threads.com/lists/mythtv/dev/303576#303576 . I think the changes are as
he suggested and fit in well with the preview generator changes in
[15029], but I'm happy to make additional changes as necessary.
Without the patch, going to the MythWeb Recorded Programs page takes
forever and results in a huge CPU usage spike (mythbackend was running at
100% on my Athlon XP 2400+ (load average > 6) for so long that I just
restarted it; on Chris Petersen's quad-core (Core 2?) backend, it was
taking 400% and recovered after a few minutes). Individual preview
generation jobs seem to work without too much issue before the patch;
however, requesting a large number of previews simultaneously overwhelms
mythbackend because of the recursive, recursive searches.
