Hum, not my experience. I run it on an old pc as a podman container, for me and my wife, exactly for the same use case of OP: auto uploading the pictures/videos on our phones. Upload is almost instantaneous. Browsing files is fine, but I usually use a separate software to index/search the photos on the upload directory. For all kind of files (documents etc) is good.
Rainbow pubes and low cut jeans? 😂
