Hi I understand boot up completes in under a second but if one needs to setup an environment to do something useful, it can take several seconds. I guess what I'm getting at is why would the fast boot matter when one still needs to setup a basic environment to complete a task? This is analogous to achieving an artificially low TTFB but actual rendering doesn't start until several seconds later. Am I missing something? Thanks
