The [Oracle 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.
