After adding the page call copy.freeReader(). You can also speed up things with:
PdfReader original = new PdfReader("EIDFormTemplate.pdf");
...
...
reader = new PdfReader(original);
Another speed increase can be done with AcroFields.setFieldCache(). There's an
example in the javadocs and it's all explained in more detail in the book.

>
> Hi all,
>
> I have a data file (CSV) and a PDF form template with it's
> fields named like the columns within the data file. I now
> want to create a PDF file with one page for every data row.
> So every page of the created PDF file should consist of the
> PDF form with the values from CSV file filled in the form fields.
>
> I've found two possible solutions on
> http://itext.ugent.be/articles/eid-pdf/index.php.
>
> The first
> (http://itext.ugent.be/articles/eid-pdf/test/EIDFormTemplate.j
> ava) does use a PdfCopy and a PdfStamper to fill the form
> fields of the PDF form template and then add the filled in
> document to the PdfCopy. The drawback of this solution is
> that it is very slow, it uses a lot of memory and it creates
> real huge PDF files. In fact using it with only 7000 data
> rows and "-Xmx1024m" lead to an OutOfMemoryError. (And in
> production we are talking about more than 100,000 data rows.)
>
> The second
> (http://itext.ugent.be/articles/eid-pdf/test/BatchFormFill.jav
> a) possible solution is to extract the fields coordinates
> from the PDF and then to simply add the form as a template to
> the getDirectContentUnder() and in the second step to draw
> the data values to the coordinates of the form fields. This
> is very fast, produces very small PDF files and uses a lot
> less memory than the first solution. The drawback is that the
> values does not automatically use the font that the designer
> of the PDF form template defined for the corresponding form field.
>
> Is there any other way that I can take to get an acceptable
> solution? Is it possible to improve the performance of the
> first solution (which is the nicer one in my eyes)? How can I
> retrieve the font used within a form field in order to use
> that font in the second solution?
>
> Thank you for any answer!
