Go to card has become slow

That's a good question.  It has been over a year since I looked at that
code, but I can't think of anything in the serialization piece that would
be an issue.  That code is all common (writing to a file buffer).  I did
not look at the actual platform file code though - could be something
there.  In this example, there is a good bit of text that is being
serialized.  It may be a good test to generate a file the same size but
with binary data (images) to see if it has anything to do with text
