Erik pointed to the Log4J write-up titled Don't Use System.out.println the other day and yesterday it was the hot story on Javablogs (I kid you not).

Because System.out.println statements and similar constructs synchronize processing for the duration of disk I/O, they can significantly slow throughput.
