Come to think of it I don't think I even have parallel boot enabled on my OpenRC systems since the Linux boot time is so much shorter than whatever the BIOS does before it hands control over (or before it even displays anything on some machines).
replyI dont have parallel boot enabled as well as it is disabled by default. Looking at this Systemd post triggered this thought to experiment with it one weekend. I have this laptop where I run Gentoo like a control freak. There is nothing in it other than the core system running as openrc services. So, I might play around adding readiness gates to those and see if anything at all can be parallelized.

replyOn which system? Is your machine, for whatever reason, re-doing "memory training" everytime it boots? This is one can be really slow.
Who knows, but any desktop and laptop I had access to in the last decade spent more time in POST or whatever than it does in OpenRC. Might be more of a case of the Linux bootup with a minimal set of services I actually need already being pretty fast even without paralellism rather than those BIOS being particularly slow. Windows for example is a lot slower there from my experience - and the difference is even more ridiculous for shutdown.
