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?
