I don't about any performance differences, but a 32bit machine has no problems utilising more than 2Gb of memory.
But a 32-bit machine does hit its physical RAM limit at 4GB,
AFAIK, it's the address space size that is 4Gb, not the physical RAM limit. Intel Pentium 32bit processors since around the PentiumPro have all had 36 address lines, so max 64Gb physical memory. For instance, I have a 32bit Compaq machine that is quite happy with its 5Gb physical RAM.
Ah. I wasn't aware of that. Does Linux allow full exploitation of the memory management hardware of those processors so as to use the full 36 bits / 64 GB of RAM? Presumably it does. And this is all x86 processors more including and since the first PentiumPro?
