Probably not. With only 2 GB of RAM, and assuming that the RAM cannot
be upgraded for some hardware-related reason, you're probably better off
running a 32-bit operating system on it.
On such a "small" machine, your 64-bit performance gain is most likely
going to be negated by the necessity of the operating system to page out
memory to the disk - or, if applicable, the solid state drive. The load
on the RAM is somewhat lighter with a 32-bit operating system.
Of course, a lot depends on what you'll be running, but just for
comparison's sake, I am running a 64-bit Mageia here now with KDE 4.6.5
and only a few opened applications, and this is my current memory
usage...
total used free shared buffers cached
Mem: 3963 2414 1549 0 2 1300
-/+ buffers/cache: 1110 2852
Swap: 7998 0 7998
Of course, a lot of that is cache, but that's exactly what makes your
system snappier. There's far less room for cache on a 2 GB RAM system.
By comparison, my 32-bit PCLinuxOS (with KDE 3.5.10) generally runs with
just over 1 GB of RAM in use, cache included. There is of course a
difference in code complexity between KDE 3.5.10 and KDE 4.6.5, but
still, I mainly attribute the memory consumption surplus here in Mageia
to its 64-bit nature.
This reminds me, there is a new x86 operating system "architecture" for
the Linux kernel in the making - and I will be checking up on its status
as soon as I've finished typing this article - called x32. x32 is a 64-
bit implementation for x86-64 processors, but it uses 32-bit pointers so
as to be more economic on the RAM. This is especially useful in
embedded devices, and potentially also for the type of machine you are
now inquiring about.
But like I said, I'm going to have to check up on its status, because I
don't know how far the project has advanced yet so far, and/or whether
it's already being implemented at a distribution level. (Frankly, I'd
be surprised, as I haven't heard anything in that regard yet.)
Just my two Eurocents. ;-)
