LazyUser.find(): 2 queries fired BEFORE touching getProfile() at all (expected 2: user + eager profile join/select)
after touching getProfile(): 2 queries total (profile=loaded)
MiUser.find() (no mappedBy field at all): 1 query
explicit MiProfile.find() by shared PK when actually needed: 2 total queries
