Either is good, amazingly large/complex web sites are run straight out of a
db (with a cache layer for common elements).

If your memory footprint can be huge, consider a serialization method so
objects can 'save themselves' and only hit the db on instantiation/disposal.

Index your tables.
Use query analyzers.

Database optimization occurs within the db itself, if you follow sane table
and index creation procedures, and pay attention to query plans everything
should be cool.
