If the process slows down it means the garbage collector of the JVM is
constantly trying to free memory. When the OutOfMemoryError comes the
JVM doesn't have any more memory and gives up.

Please see http://xmlgraphics.apache.org/fop/stable/running.html#memory
for tips to handle OutOfMemoryErrors.

If possible try to switch from a DOM as input document to generating SAX
events. That can reduce memory consumption further. It can also be faster.
