- More parallelism
- More efficient asynchronous redo read, parse, and apply
- Fewer synchronization points in the parallel apply algorithm
- The media recovery checkpoint at a redo log boundary no longer blocks the apply of the next log.
Noconfiguration is necessary, although we can use new parallel recovery wait events for tuning if the default apply rate is not satisfactory.
