Moving to full 64bit should indeed be a better choice, you would
think, yet many of apps & plugins are still 32bit only.
I believe that this is fluff and not fact. There are a few apps
which only have 32bit plug-ins for certain capabilities, ie: I still
run 32bit firefox and plug-ins and 32bit java. But *everything* else
on my 10.1 system *is* 64bit.
But why? Do you run applications that need a 64-bit address space? If
not, it's only more execution overhead to move nearly twice as much
data around to get any given task done. The fact that the main system
busses are 64-bits wide does not negate this overhead. Almost
everything a desktop computer does is RAM-limited (this is even true
for most CPU-intensive applications), so using a lot less RAM really
does help.
64-bit machines don't use much more RAM. I asked Novell about this, and
they suggested that the 64-bit version of SLES 10 only uses about 1%
more RAM. There is a difference, but it's not that big. Do you run
64-bit, Randall? I do at home, and I don't really have any memory
problems (except with a certain Java application, but I think that's a
bug). Also, if you're planning to go over 2Gb, it's the way to go,
AFAICS. Things start to get kludgey in the OS above that limit with
32-bit, and it can't help performance.
