i have ~16k in my library most of the time and it doesn't seem to cause major issues. > When I > start darktable, *some* of these images will have thumbnails that show up > instantly - but a lot of them will start out as just grey boxes that fill in > over time --- seems to take about 0.2 seconds per image - I normally have a > grid of about 150 images visible (on a 30" monitor), and it takes about 30s > for all of the thumbnails to populate... if you're using 1.2-to-be (git master) and have never_use_embedded_thumb=false set in your darktablerc it'll load crappy exif thumbnails a lot faster (for my camera, these are like 160px wide, enough for your kind of zoom by the sounds of it). that will of course not speed up loading of images you have already processed to hell so that the embedded thumb is out of date (we don't ever write to your raw originals). > I could live with the 0.2 seconds per thumbnail if it was just once per > image - but it isn't... If I browse for a bit and then stop and restart > darktable, most of the images will again show up without a thumbnail and > I'll be back to waiting 0.2 seconds per image... there's also a setting cache_compression (set in preferences in dt) and i'm using cache_memory=1000000000 to give it some more space for thumbs. compression will make your thumbs even more crappy and a little slower, but you can play with it and see if it works for you. > I don't understand why some thumbs show up instantly after a restart, but > the majority have this delay... > > This makes quickly browsing through a large collection very painful... > > Is there anything I can do to get the thumbs to be saved from session to > session, so they'll all load quickly? > > Thanks!! > > Warren > > -- > Warren Baird - Photographer and Digital Artist > http://www.synergisticimages.ca > > ------------------------------------------------------------------------------ > Everyone hates slow websites.
