Like most of us I think, I really, really wanted to like nextcloud. I put it on an admittedly somewhat slow dual Xeon server, gave it all 32 threads and many, many gigabytes of ram.

Even on a modern browser on a brand new leading-edge computer, it was completely unusably slow.

Horrendous optimization aside, NC is also chasing the current fad of stripping out useful features and replacing them with oceans of padding. The stock photos app doesn't even have the ability to sort by date!. That's been table stakes for a photo viewer since the 20th goddamn century.

When Windows Explorer offers a more performant and featureful experience, you've fucked up real bad.

I would feel incredibly bad and ashamed to publish software in the condition that NextCloud is in. It is IMO completely unacceptable.
