I doubt that the speed has anything to do with the speed of the language,
as the problem here is seeking on the disk.

Regardless, if you use Java 1.5 or newer, I sincerely doubt that the speed
difference between Java and Delphi is substantial.  Although I do hear the
myth that Java is slow all the time.

In any case, making your changes public would help a few people, I guess.
