I have two versions for comparison, one that caches and one that doesn't. Both are called "Docker Copy Only" and are based on your yaml and docker setup as seen here: https://github.com/marcusradell/monadium/actions. Any clue why the caches isn't kicking in?
I would assume that the most time of those 2 steps is actually spent compiling your code. You should be able to get considerable performance gains by using sccache and caching sccache's cache folder so it's shared between workflow runs.
The docker bits are more complicated. cargo chef makes it so you that docker can actually cache the layers for compilation, so past that you just need to cache the docker layers. The issues I've had were that restoring and saving the docker layers with github actions started taking more time than just rebuilding everything.
