Josef 'Jeff' SipekFun fact: Using RDP to access #AdobeLightroom 6 on Win7 vm with photos on a samba share is more responsive than using #Digikam 8.2 natively on *nix with photos on NFS.
I think this says a lot about Digikam's scalability.
AB1WX Ryuji@jeffpc (1) Lightroom makes preview images in local drive next to the SQLite catalog file, so access speed of the original copy (RAW files) is not that critical. You probably knew that. (2) if you figure out how to run the current Photoshop CC and Lightroom Classic on any PC UNIX please let me know... can't wait to say goodbye to Apple.
@ab1wx (1) digikam also uses a sqlite database (can also use MySQL IIRC), I don't know if they include previews in it or not, but it looks like digikam likes to reindex everything waaaay too often, which takes a while with tens of thousands of photos
(2) my interest is in LR 6 because that's the last perpetual license version (and not subscription) and I have one. With that said, I've been meaning to try Lightroom under Wine but haven't gotten around to it.
@ab1wx For example, when I create a new directory in the digikam UI and it spends the next minute indexing everything with the UI more or less locked up.
@ab1wx It looks like it has uses a sqlite db for thumbs as well:
$ ls -lh ~/.digikam
total 2531963

@jeffpc I also have CS6 license but the MacOS version... I could use it on Mojave or High Sierra. but I need new camera support so I just use CC now.
@ab1wx Before I got LR6, I had LR4. When I got the Nikon D750, LR4 didn’t support it but Adobe had a free DNG converter tool that knew how to turn D750 NEFs into DNGs. Just FWIW.
@ab1wx I thought the perpetual licenses were for both Windows and MacOS. I never really paid attention to it, but I recall seeing a "mac/win" somewhere when I bought it way back when.
Of course, running Windows just for LR isn't really a step forward from running a mac just for LR.
