The author reframes Nix evaluation as a scheduling problem, arguing that repeatedly evaluating expressions for CI, deployment, and daemon use cases is inefficient. They introduce Evix, a Rust-based tool designed to optimize this inner loop by treating derivation listing as a scheduling task rather than a one-time cost.
Background
Nix is a functional package manager and build system where evaluation can be computationally expensive. Tools like nix-eval-jobs are commonly used to list derivations, but performance bottlenecks persist in high-frequency scenarios.
