Re: x86-64 on i386 (was Re: Promoting i386 version over x86_64?)

You reject my metric, I reject yours. Something of an impasse.

I'm not rejecting the performance metric at all.

(It's also not too hard to make firefox use more than 3GB of virtual
address space, though I admit you do need to work at it a little)

Only because it's obsolete. Multi-process browsers use a lot less RAM per process.

What was the point of this conversation again?

For those who can't sort by thread in their MUA: To ask that 32-userspace-on-64 be supported (it pretty much all works, except for yum updating certain things, like the kernel), as there are definite benefits to a 32-by-default userspace.

Some people chose to argue "But you should just run 64bit completely", despite people already having described one reason to 32bit (memory usage). And from that we somehow got into a "x86_64 versus x86" thread of doom, with (IMHO) much missing of the general point.

Anyway, enough.
