I forget the exact specs but it had close to 200 cores and a team of highly paid dbas that had optimized every aspect. Even the worst of queries would come back instantly.
We had a database growing by around 200GB of relevant data per month. While I'm not a fan of Oracle having worked there long ago, that database was unbelievably fast. They moved to MySQL years later and it required a much much bigger tin after being heavily optimized.
