Using various online suggestions found in forums and blogs on boot and setup adjustments I had managed to reduce a Raspian setup to boot headless and loading several instances of PD to run on a couple of reserved cores (using jack2) in about 23 seconds. Some of the obvious ones were purging any apps that would not be used as well as reducing the services. I think to remember that disabling networking made quite a difference as it avoids several ‘waiting’ loops, but obviously that restricts possible applications significantly and is therefore only useful if you are after a ’standalone’ audio setup.
I wish I would have kept a conclusive list what I had done and what worked, but as I had several quite severe fails in the process and I had tried that while being new to pi and linux, I ended up not quite having a complete overview of the final version and steps. I’m very interested in the piCore os, thanks Thomas for making compiles available for it!

Hi all, i am a big fan of the piCore os. [1] That is a stripped down read-only linux distro with loadable modules for alsa, pure data etc.. Boot times are considerable shorter than with raspbian. Of course it also needs some dedication to get used with it.
I have compiled pd, jack and libfftw3 for piCore 11, to be found here: https://grrrr.org/data/dev/picore/piCore-11/

It takes about a minute for the pi to boot. There is not much you can do about that.

Hi everyone, long time reader first time writer.
I’m wondering what people’s experiences are with regards to the startup time for running a patch on a raspberry pi.
For various reasons I’ve started to use Patchbox OS to auto-run my patches on startup, which is very reliable and consistent however it usually takes about 60 seconds from switching on to making sound. This is on various models of Raspberry Pi 3.
Has anyone managed to speed this up? I haven’t tried the Raspi 4, perhaps that is significantly faster?
Thanks, Yann
