Subject [jira] Created: (DERBY-262) Use Java 1.5 NIO for improved performance

Use Java 1.5 NIO for improved performance

         Key: DERBY-262
         URL: http://issues.apache.org/jira/browse/DERBY-262
     Project: Derby
        Type: Wish
  Components: JDBC, SQL, Network Server, Store, Services  
    Reporter: Eric Solberg

Are there plans to take advantage of JDK 1.5 NIO in Derby?  This should give a substantial
performance benefit.  In a simple test, processing extremely large PDF files (80+MB) into
individual pages, I saw 3x-4x performance improvement using memory mapped files.  This was
without doing anything 'smart' to squeeze out even more performance.
