Hi,
You should not compare tkprof outputs with V$SQL,V$SQLAREA. Because,
recursive/child statistics are included in their parent statements in these
views. But, tkprof substructs recursive statistics. I mean tkprof reports real
values for statements, but dictionary doesn't.

Steve,
Query V$SESSION_EVENT for the SID of that session. If you see the
wait-event db file scattered read change during the query, then it truly
is doing I/O, like it or not. It is more likely that the CACHE attribute is
not working as you've apparently assumed it does, rather than there
