looks like you have quite a good expertise on Arch Linux and audio, quite a rare combination maybe can you give me some hints into how to make faster booting Archphile on RPI3 without compromising the sound? The setup doesn't need to have any visual interface or any network connection, just MPD, MPC terminal commands. MPD will be controlled through Python Serial lib, via USB. So basically I just need to have USB ports for accessing storage, Serial, and Bluetooth dongle, and running MPD and Bluetooth commands.As setup will be in the car it will be really annoying to wait more than 10 seconds for bootup of RPI. For the first steps i could just disable all unneeded packages (MyMPD, Avahi, etc.), but what could be done next? Do you think its possible to reach 5 seconds boot time?

thanks man, that was a nice feature. I am getting these results. Red ones i understand i can disable in my case, green i can launch on demand after bootup. But it doesn't cut that much now loading of all system time around 17s. Is there any other services i could disable? and other tricks to make boot faster?

Most of these services are important. I would not stop them, maybe move the start process to a later point where its possible. You'd have to alter the systemd unit for that.
You can further do some
My suggestion is, take a look at the socket activation topic.

then i will stick to your advice and won't experiment with those processes
I borrowed some knowledge from here Himesh's Blog: Fast boot with Raspberry Pi
What about overclocking? can in theory it harm sound quality?

all working nicely on an updated rpi4
A few posts ago, there were a lot of users, myself included, who had problems with some additional scripts for archphile...
GIven my recent experience with a rpi4, I thought I could give some updates to this and I could share some happy news that since i started to use a rpi4, updated with the latest eeprom firmware, all is once again well in the world of archphile!
Cut a long story short, I was able to buy a rpi4 2nd hand. I had all sorts of problems with network instability etc, until I decided to see if it had been updated to the latest eeprom. i stumbled my way through an update and was able to update the eeprom and reinstalled archphile with all the previous tweaks that brought all sorts of troubles before.
Then I realised that tuxx had already included the means to updating the rpi4 eeprom firmware on page 39 of the manual! d'oh!
I've let it run for a week now, 24/7, and all has been well.
I have all the tweaks from p38? of this thread, plus all the lights disabled, wifi power management off and it is running beautifully with my oldish pi2design 502DAC HAT.
Message is - if you had problems with rpi4, please check you have latest eeprom firmware - that may be it. I am a happy camper. I also think the rpi4 with a HDD sounds discernably better than a rpi3b+.
On another note, I have tried using a flash drive as well as my HDD and I think the flash drive sounded better than the HDD, and I now hypothesize may be a reasonably competetive alternative SQ wise to a SDD.
How much power does a USB flash drive consume?
I might try one of these in the next few months - SanDisk 512GB Ultra Fit USB 3.0 Flash Drive - and will see how I go.
But wait, I've just had a glance and the 1Tb Samsung SSDs are offered at a good price so might go that way anyway.
Hope this helps anyone interested in archphile. If you ask me archphile+rp4 is the bees knees!
