Hi :)  

Are Cpu cycles to do with multi-core/multi-cpu?  If so it's presumably possible for 32bit apps to 
take advantage.  I think it's just a fluke that most of us think that 64bit machines tend to have 
more than 1 cpu/core and 32bit ones don't.  Both technologies became well known around the same 

Apparently the 4Gb Ram limit is a limit of the OS, not the apps.  If the OS can read/write to more 
ram then i don't think the apps would be restricted.  Apparently OSes that are 32bit could read 
more Ram with a different kernel module.  With Gnu&Linux it's possible to swap-in the different 
module and i kept being  told that "it's really easy".  Something like the pae-something module.  

Ram is used more efficiently by OpenSource programs, especially when using quite a few at the same 
time.  My whole system is OpenSource apart from a few fonts and a couple of codecs and i seldom 
need even 1Gb.  Movies and even fairly hefty games seem quite happy.  I figure that if bits of my 
ram detiorate over time then i could always swap the sticks around to use the ones that aren't 
getting used at the moment.  

If it feels like LO/OO are bumping into ram issues then it's more likely to be the limits you set 
(or the default ones) in

Tools - Options - Memory

If you imagine wires or cables as lanes on a motorway then double the number of lanes can carry 
double the number of cars.  It's just that you don't always need to have that many cars on a 
section of motorway.

Okay, I'll betray my ignorance. What would be the difference or advantage
of running a 64 bit LibO vs. a 32 bit LibO?


IMHO, the practical difference is nil for a typical office use. Some large
databases will require 64 bit because 32 bit is limited to 4 GB.

How many LibO user are having wn64 machines? Or better what is the
percentage of win64 users in the LibO community?

I'm a Linux user, 64 bits of course, but I have one, 1, count 'em, one
computer that has 64 bit Windows 7 on it.  Then again, there have been
64 bit versions of Linux going back 17 - 18 years and I was running 64
bit Linux for over 5 years, before I had 64 bit Windows.

Since Libreoffice is a Office product . I don't believe you will see a big
differential in performance as a user . From a programmer view , you can
take advantage of the cpu cycles and memory usage with a 64bit system.
