Viewing large collections in lighttable is slow
Viewing large collections in lighttable is very slow. The thumbnails take a very long time to show up. Here's what another user reported on darktable-users, including a video comparing darktable with digikam on the same set of images:
The problem seems to be that darktable doesn't do disk-based caching of thumbnails, so if all the thumbnails don't fit in cache to page through a large collection thumbnails need to be generated again. Here's the discussion on darktable-devel on potential ways to change the caching behavior to fix this:
Basically finding a low-impact way of caching small thumbnails on disk to use in the lighttable view could potentially make it much faster.

- Affected Version changed from git development version to git stable branch
- % Done changed from 0 to 100
- Target version set to Candidate for next major release

This is fixed in current git with the new disk cache, will be in 2.0 when we release that.
