* Increase the log buffer size. This will reduce the likelihood of the log buffer filling forcing the log writer to immediately write possibly with less than its full 1MB potential.

* Increase the _log_io_size parameter. Changing this parameter to 2048 will ensure the typical 2,048, 512-byte operating size blocks will also generate a full 1MB write.

* Use the commit write facility with both the batch and nowait options. With a full understanding of the potential risk of losing committed data, the commit write facility's batch option will specifically batch redo entries to maximize redo writing affectivity. Plus, the nowait option tells the log writer background process to write in asynchronous mode, which will most likely result in a near-immediate completion of writes.
