If you are using the XSL functions to assign primary keys to records, consider using the built-in native sequencing support in the adapter. Sequencing support obtains and caches 50 keys at a time by default. Caching improves performance by reducing the number of round trips. The chunk size can be controlled incrementally by modifying the sequencePreallocationSize connector property.

Other interesting performance improvements for DB adapter relevant for Exalogic - I will look more into that later.
