Subject Re: [jira] Created: (DERBY-262) Use Java 1.5 NIO for improved performance
Date Fri, 06 May 2005 03:24:35 GMT
It would be great to do this.  Once I get a little more familiar with 
Derby, I'd love to do this as a project; I think it's more than a 
one-person project so anyone else who'd like to join in...

But first things first, I'm still learning how the test framework works 
and how to submit a patch :)

> 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.
