Improve Boot Time #1

Open richtamblyn opened 3 years ago

From plugging in power to establishing a connection to the Spark, it can take on average 1 minute, 9 seconds. The 'Booting' message is shown around 40 second mark but that still feels like an age. Can we make it better?

If we didn't need the DHCP and Networking services for the web interface that would shave off at least 15 seconds.

This looks very interesting... https://www.furkantokac.com/rpi3-fast-boot-less-than-2-seconds/

Despite reducing the overall boot time with various OS tweaks (I can login to the console after 12 seconds), the 'Booting' message still only shows up around the 40 second mark and I'm not sure why yet.

I'm going to investigate changing to the PyPy interpreter this weekend to see if that speeds up the initial start time.
