Our current build systems can turn GCC 4.7 around in about 24 hours.
The enterprise hardware we anticipate using will take that down to about
12 hours. If speed of build hardware is a consideration, where do you
draw the line?
IMHO, at MOST 50% longer (factor 1.5) build time, and that's already being
nice. You're off by a factor of 4!
No secondary arch is going to get to the speed of x86_64 in the
foreseeable future, so it's effectively a way to keep PA an exclusive x86
club.
That's exactly why we should stick with only x86 as primary architecture(s)
in the foreseeable future.
I think the real question is, for the developers of on devel-list,
how
will longer builds for one arch than another affect your workflow? If
builds on two architectures start at the same time, but one takes longer
to finish than the other, how will that impact you? Right now you'll
still be able to see and use the results of the faster build before the
slower build completes, so are you materially impacted?
See the other replies: chain builds, updates, platform-specific errors,
build results. A lot of things depend on the builds to actually complete.
