New subject: Pros and cons of 64 bit Linux

14 Aug 2009

I recently changed from a 64 bit install to a 32 bit install (also Gentoo). 

I have 4GB of RAM and that uses the highmem function.. there is supposed to be an
extra step to address the RAM.. but I don't see any negative impact on
performance at all... Only thing I have noticed is that more apps are able to
compile, I was going to use VST's .. but I have so much hardware that I never
really get beyond LADSPA plugins to compliment the hardware.. 

I also am using an NVIDIA video card (7600GS silent).. simply because my dual
monitor system works pretty much automagically with the nvidia-settings tool... I
have onboard ATI Drivers on my mobo.. but have disabled them and don't intend to
use them due to shared RAM... 

Even though RAM is cheap I believe having discrete video RAM is better for audio
performance...strik me down if I am wrong.. I am open to suggestion.

 I have my system running 64-bit Gentoo with no real
problems.  32-bit and 64-bit software run on the system as long as there are
corresponding libraries for the
app to link to.  Ardour is compiled as 64-bit which means I cannot use VST's in
it, but dssi-vst works fine since Wine seems to be 32-bit and they are run as a
separate process from the 64-bit audio apps.  I haven't seen any problems with
Flash/Java/ or media players.  I can't address the video card as I use an Nvidia
with the Nvidia 64-bit binary driver which works fine for me.  The reason I
switched to 64-bit was that I upgraded to 8 GB memory for rendering in blender.

Hi Ismael!

   64bit can address more memory (I think this relates to RAM. I think the

integer size used by the CPU is larger. So good for large numbers? and for a

lot of mem. Some people also claim in RT apps it's faster, but I don't really

believe that.

   32bit: All the wndows dlls will run. I guess you'lll also find more

precompiled half-closed software pieces for 32bit. Mplayer and some other

programs can use .dll and other windows shared libs to support audio/video

formats and maybe more. Java shouldn't be an issue. You should only need the

java interpreter and the rest is byte-code, that's supposed to be the same for

all systems. but 32bit might also be nice if you're going to use VST(I)s,

because they too are pieces of 32bit windws software. But I'm not sure how far

the technology has gone here.
