under 500 ms. unless people are doing some form of XIP, because binaries
are getting so big these days that just the load/link times are getting bad.
Did you statically link or pre-link?
Thanks - any details on this would be great. I'm trying to find examples of
quick boot, to use for the "state of the art" for my status presentation
You must specify what means boot time because boot time can be up to theAgreed. It's valuable to see new boot-time enhancement techniques. But
we should be specific about what the limits are, relative to other techniques.
One appeal of the checkpoint technique is that it appears to be general-purpose.
I'm not sure what technique is being proposed in Artemi's project.
As an aside, I'm not sure why checkpoint isn't referred to as hibernation, but I
haven't looked into the details.
