Eval cache for IFD-heavy evaluations (Question / Feature Request)

[blaggacao]

Is eval cache supported? The readme doesn't really mention something.

If not, is it in-scope?

[grahamc]

Builds that happen during evaluation time will be cached, is that what you mean?

[blaggacao]

is that what you mean?

Actually, I was referring to these:

          ~/.cache/nix
          ~root/.cache/nix

It still can rip of +- 30s (very precious eval) cycle time or so in some adverse scenarios based on experiences with this implementation.

In the future, we may support evaluation caching, but it isn't part of the goal just yet. Good idea, though!

[blaggacao]

Probably you could somewhat leap-frog from here.
