Hi there,

I got an e-reader and one of the books I wanted to read was the TEI Lite
Guidelines (generated from
http://www.tei-c.org/release/xml/tei/custom/odd/teilite.odd at
http://www.tei-c.org/ege-webclient/).

Everything works fine, except that the TEI Lite ePub file takes longer
to navigate in the e-reader. This is specially noticeable when you go to
the next page beginning a new section. In this case it takes more than
10 seconds, when going to the next page only takes about a second in
other files.

I experienced this issue for the first time with the Guidelines.epub. I
thought it was caused by the big size of the archive. But after I
experienced the same issue with teilite.epub, I thought it might be the
way ePub files are generated from TEI files.

Comparing two files: teilite.epub and another bigger file that works
fine, gives the following results:

teilite.epub contains 35 files. Compressed size is 314.2KB and
uncompressed size is 2.8MB, being the compression ratio almost 11.06%.

http://www.feedbooks.com/book/4960.epub contains 128 files. Compressed
size is 2.3MB and uncompressed size is 6.7, being the compression rate 35%.

The higher compression rate might be the culprit, although I experience
the problem also with other files than have a much lower compression
rate
(https://code.google.com/p/epub-samples/downloads/detail?name=accessible_epub_3-20120301.epub).

I don't know what is wrong here. Does anyone have a clue? (I guess I
won't be the only one who is experiencing this.)

Many thanks for your help,


Pablo
