Normally when I work from home, I use OOo (3.2.0) on a Linux 
workstation with 8 Gb of RAM, a 2.6GHz quad-core AMD Phenom X4 9950 
CPU, fast disk drives and other performance-oriented H/W.

This weekend I had to do some maintenance and my favorite box was down 
so I used a 'slower' PC with slower drives, 4GB of memory, and a 
slower CPU (dual core Athlon 64 @ 6 GHz), under Windows 7, and 
performance-wise OOo 3.2.0 on it ran rings around the faster Linux box. 
(I had never tried it there before on anything longer than a grocery-
list spreadsheet.)

Is there a known reason for the performance difference between the 
Windows version and the Linux version?  Or am I seeing something else 
probably unrelated to the software itself?

From the load meter, I notice that on Linux, OOo seems to max out only 
one core on the CPU - however, it seems to split across both cores on 
the Windows 7 machine.  While I expect that this has something to do 
with it, I am hard pressed to believe that this is the single cause.

As a test I 'borrowed' a novel my wife is working on (about 900 pages, 
no illustrations, all one long .odt document) and here are the 
comparative times (in seconds)

                                        Fedora 13

                                        --------------- ---------

I really like OOo and have used it (and even StarOffice before OOo was 
available), and have no intention of changing tools.  However, the 
performance I am seeing here worries me.

Does anyone have any insights into what I am seeing here?
