find / -name *.sqlite -printf '%s %p\n' 2>/dev/null | sort -nr | head -n 1
The winner is `favicons.sqlite` from Firefox profile directory, which is 40 MB.
mdfind "kMDItemDisplayName == *.sqlite" -0 | xargs -0 stat "-f%z %N" | sort -nr | head -n 5
should be fairly fast because mdfind uses the spotlight backend and already has this data cached.
