A good guess. I changed the code according to your suggestion and it reduced the processing time from ~25 to ~3 seconds. Better but still ridiculously slow. When I generate the same XML document by concatenating pre-fabricated strings, as suggested by Friedrich, the whole process takes just 10 ms according to system.time.
