instead of checking hit ratios, try looking at wait events in
v$session_event, v$system_event and v$session_wait.
also -- how many indexes are on these tables? How much data is in the
tables? If the indexes are doing constant block splits on the insert you are
basically rebuilding the index each time.. this can have a major impact on
performance.
