Do you use raspbian or other (arch-ubuntu server) linux on rpi?

Sounds interesting the cljs thing, I will test on the next week.

Btw I work with Arduino-ESP sensors and RPIs, but mainly with C and just at serverside with Clojure/Java.

We use a buildroot-based image. We do heavy lifting in C++ and use node for high-level management, monitoring and as a tunnel to the server side. Our C++ code is heavily multi-threaded, so we are not concerned with idle cores. We do not manage js modules exports properly for CS to invoke JS, so we used shadow-cljs to build a library to be invoked from JS. I must add that I failed to convince the team to use CS over JS, so we ended up with no CS code on the rpi

@kulminaator I would be very interested to know if you find the zulu jdk performant enough to do any meaningful work on the rpi
