I got really tired of waiting for builds on my lowly dual-core Atom machine, so I went out and bought a nice fast machine with an i7-4770K and a Samsung SSD. Full builds are now screechingly fast, over 10x compared to the Atom.
But when making a tiny change, I still have to wait for do_rootfs. Since this is a single task, it runs on a single core, so it only runs maybe three times as fast. For my Gumstix stuff, it takes five minutes instead of something like 15. That's a meaningful improvement, but it still seems long when the task implementing the minor change took, oh, five seconds. Since it's the one task that _always_ gets executed, it seems like a bottleneck that should be addressed. Is there any way, in the future, of breaking do_rootfs into multiple threads, so they can take advantage of multiple cores? Or has something like this been tried already, and found not to produce much of a speedup? Or is the process intriniscally sequential? -- Ciao, Paul D.
