I had a similar problem with a command line utility that looped through
several thousand objects running an outputXML() function I wrote that
basically put the data into a standard XML format.
I had originally made it do:
String ret = new String();
For (int I=0; I<objects.length; I++){
ret += objects[I].outputXML() + "\n";
}
Return ret;
Then put the string into a file, but the time taken increased exponentially
as the number of objects increased. When I changed it to:
PrintWriter fileOutput = new PrintWriter(new FileWriter(new
File("outputFile"));
For (int I=0; I<objects.length; I++){
fileOutput.println(objects[I].outputXML());
}
It was far far quicker (from several minutes to a few seconds).
I know it's not an exact solution, and puts the output into a file rather
than to a variable, but that's because I'm using a FileWriter for my
implementation, and I'm sure there are other ways to use a PrintWriter
rather than outputting to a file that would solve your problem.
Hope that's of some help though.

P.S. Just noticed Entourage insists on capitalising various commands in the
above code, but you get the general idea.
