On svn export of jackrabbit trunk it takes ~1 minute (note that in your code you increased
the counter two times in the loop. Thus, I've just half of the units than you had).
However, it's factor two slower than on your machine. The size of the attached data, however,
does not seem to be the most limiting factor, right?
(27 MB & 3k files -> 1 minute; 240 MB & 6k files -> 3 minutes)
