That's the first time I see a lady say that. I thought it was a consolation of us, middle-aged, chubby DBA males. Joking aside, the buffer cache should be increased using the same principle as for everything else: you increase the buffer size when you start seeing free buffer waits in your V$SYSTEM_EVENT. The basic principle of the event-based tuning methodology is to try fixing that what sessions are actually waiting for, instead of computing BCHR, horoscope or your personal lucky number.
