I ran the code you posted on my local box and the results are mostly 
comparable. However, I got a big performance boost when using the 
LocalFileSystem on a Reiser4 filesystem (Linux 2.6.8): between 4 and 5 
times faster then ext3!

The reason I'm doing this is because I want to explore whether Reiser's 
support for metadata [1] can be somehow put to use together with

Is this CQFilesyste proprietary of Day or is it available to the public?
