> 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.
