Exclamation Limits bookdesigner or LRF?

When assembling and producing a new book,I come to think I've reached the maximum of Book Designer's, or the LRF capabilities/capacity..

For a while now I'm converting bibles using the 'bible framework' as base frame (posted here).

I previously thought I had reached a maximum, as some errors started to appear when converting large files from .doc format to .lrf.

Later on I discovered if I created my ebook as a basical HTML, I could take bookdesigner even further.
Bibles posed no trouble with their near to 1000 chapters (bookmarks), and 3000 href's (hyperlinks) per file.

Within that frame I think I have reached a limit here today!

As I was creating a 'bible commentary',using the same framework as a regular bible, I found I could no longer get past Proverbs 30 with this edition.
The text after this would simply be cut off; not encoded,as if the book ended there.
Matthew Henry's complete bible commentary edition is rather.. VERY large in size.
Here are some numbers to give you an idea:


-After some pruning, the source (HTML page)could be fit in a 21,6MB uncompressed HTML.
-The amount of characters within the source html where about 22,7 million characters, and about 15 million characters from beginning to Proverbs 30.
-compressing that file using Winrar's best compression, resulted in a 4,32 MB file,or 19% of it's original size. (compare this to the King James Version Bible, which takes about 3,3MB in size uncompressed,or the Old testament is 600kb Compressed).
-A chapter of a book (like eg: Genesis 1) in the commentary took on average 30 sony reader pages of text @ 8 pt as commentary to that chapter, and about 1 full display of text per verse.
-The resulting .lrf created from the source HTML (including it's 33kb cover.jpg) was around: 10,5MB in size (all the way from Genesis to Proverbs 30, or about 70% of the total size was done).
-The amount of pages on 9pt encoded .lrf file equaled about 9952 pages on the Sony Reader (70% of the book got encoded).
-The amount of pages on 8pt encoded .lrf file equaled 7500 pages straight on the Sony Reader(70% of the book got encoded)!
-The encodingtime on a 1,66Ghz Core2Duo took about 35-45 minutes (to convert from HTML to LRF)


Am I the first who hit Bookdesigner or lrf limitations?

Anyways, if anyone knows a solution to this, you are more then welcome if you could help me out!


For those interested in the book, I'm working on getting it uploaded soon!
At the moment I finished the Old Testament commentary, by chopping it in 2 pieces.
If there's any fix to this limitation I might consider uploading the OT commentary in one piece, but I don't know if there'll be a solution any soon or not...

Perhaps this info is or was useful to some who plan on making large books available on the reader.
I don't know where the limitation hits in, but if you get close to any of the numbers mentioned above, you might want to test out if it can be encoded or not!

Greetz!
