The difference you point out has _nothing_ to do with optimization and is unavoidable for now. That is the choice between a 32 bit operating system and a 64 bit operating system (on both Intel and AMD architectures). Eventually 32 bit systems will die of old age as _all_ programs run fine on 64 bits and that directory will be erased. Distributions and packagers will surely make a big party when that happens. -- Fernando > Perhaps x86_64 will be fine-grained enough to define a pleasant platform > seen from an audio developers perspective?
