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
time.

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

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.

CPU Cycles is the process the processor takes to complete a command.
Multiple cores came about due to the current CPU overheating above 4GHZ .
So they started adding more cores to the existing processors to give you
more cpu threads to process commands. So in theory you can have a 3GHZ CPU
with dual cores (2 central processing units) to get the result of a 6ghz
processor.

You are correct, the 4GB limit was imposed by the operating system . 64bit
has been around for years, I believe someone else mention this on the
thread, its not new and unix/linux has been using it.

I like that ,
