Do you see a better way of doing this with PDF::API2?

First off, let me preface this by saying Thank You to all of you who 
have helped me understand how PDF::API2 works (and a BIG thanks to 
the author!), without it I would not even be 10% of the way through 
this project.

Now here is the next question I hope you can help me with. FYI all of 
this is working right now.

1. I am currently creating a multi-page pdf using text that is input 
by the user.

2. I then save this pdf into a file.

3. I then re-open this pdf and extract out the individual pages into 
seperate files (reason for this is they may want to view just that 
page and I need the individual pages for step 5).

4. I then create a new pdf.

5. I then open and insert the individual pages into the new file, 
along with any photo pages that were made (these are done in a 
seperate section and a single page pdf is made with the photo) using 
a page map, as an example, if I have a 7 page pdf (filename-1.pdf 
through filename-7.pdf (created in step 3)) and my page map says to 
insert photopage-1.pdf before page 3 and photopage-2.pdf before page 
6 I will end up with a 9 page pdf containing:
filename-1.pdf
filename-2.pdf
photopage-1.pdf
filename-3.pdf
filename-4.pdf
filename-5.pdf
photopage-2.pdf
filename-6.pdf
filename-7.pdf

6. I then save this new finished pdf

The above steps are important, because if they make a new photo page 
I create the page and then jump to step 4 to make a new finished pdf.

Now the question is, how can I make this faster program wise (it isnt 
THAT slow, on a 10 page pdf it takes 45 seconds or so)? The one thing 
I can think of that would work is if I could combine steps 2 & 3, so 
that while I am making the multipage pdf I can save the current page 
as a new pdf without closing the multipage pdf. Is it possible to 
save a page on the fly with a new name and not close the current pdf? 
Or, can I copy the current page contents into a new pdf structure and 
save that?

Now I will definatly increase the speed when I add more memory to the 
server I am testing on, and the server we will deploy on will be the 
fastest one possible with the most memory possible, but if I can 
speed it up on my 1.5ghz system with 256mb (I know) then it will THAT 
much faster on a 4+ghz with 2gb+ of ram.

Thanks in advance
