> [Nextcloud] was a resource hog that was eating up too much everything on my modest VPS.

I've seen comments like this in multiple occasions. Is it really that bad? I guess if there was a flagrant performance bug, it would have been sorted out with time, so the only remaining explanation is that the code is really poorly laid out, or with design flaws that cause so many performance problems for users.

However next to each "it's a resource hog" there is always another comment saying "it works fantastically well", so I never know what to think (sort of trying it myself, but I'm not that interested in the issue)
