I don't post questions on forums often, so forgive my ignorance. I'm using a RPi 3 running Raspbian to view media on the Plex website using Chromium. Currently, my Pi takes about 70 seconds to boot, run my script to open Chromium, and navigate to the Plex website. I'm trying to get that down to under 30 seconds. Unfortunately, I am a noob when it comes to RPis. What can I disable to make this process faster?
I know I could simply use Minibian, but I am trying to become more familiar with Raspbian for a school project. Should I use Buildroot? Should I use systemd? Would
systemd-analyze blame be helpful to find what to disable or am I likely to just break my Pi disabling stuff? Should I make a custom kernel? What would be most effective for increasing boot speed (into Chromium)?
I appreciate your help. Sorry again if this is the wrong place to start this thread or I have asked the question wrong.
