- 64bit binaries consume more space on disk than 32bit ones.
- 64bit processes consume more RAM, than 32bit ones.
Indeed, 32 bit system suffer from the limit on address space (4 Gb),
which is statically divided between kernel (KVA_PAGES) and userspace.
And userspace address space is further divided:
On amd64 address space so big that your can forget about KVA limit or
limit on mmap size.
I think 32bit OS is reasonable choose for workstation with RAM < 3Gb.
And even for small servers (like router on Soekris board with 512Mb RAM).
