Hello Roman, *,
interesting bug ... ;) I tested it with LO Version 3.6.0.2 (Build ID: 815c576),
installed Germanophone Help as well as Lang pack, under Debian Testing AMD64.
My system is an IBM PC with an AMD Athlon X2 6000+ CPU (Dual Core 2x3.0 GHz)
with an 750 GB WD7500AAVS HD w/7200 RPM, and - IIRC - w/3GB of RAM. If I open
your attached Big book sample, it needs
<quote>
real    0m10.015s
user    0m8.497s
sys     0m0.304s
</quote>
just to open the file. If I use the PDF Export with your mentioned options, I
get
<quote>
real    3m36.746s
user    3m30.457s
sys     0m1.536s
</quote>
... :(

With my installed LibreOffice 3.5.5.3 Build-ID:
7122e39-92ed229-498d286-15e43b4-d70da21, I get
<quote>
real    0m20.843s
user    0m13.001s
sys     0m1.468s
</quote>
just to open the file ... :( Exporting needs
<quote>
real    4m23.457s
user    4m29.125s
sys     0m3.068s
</quote>
, so in my case the older version is slower than the newer one ... :(

Just out of interest: Which Java are you using? Mine is
<quote>
java version "1.6.0_24"
OpenJDK Runtime Environment (IcedTea6 1.11.3) (6b24-1.11.3-2)
OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)
</quote>
or openjdk-6-jre 6b24-1.11.3-2.
HTH
Thomas.
