Tvix (79246855d1a0fd9b81be113b16a56379c7641aa1) vs nix (2.19.2) evaluation of the hello package
View 0_description.md

Tvix is a new implementation of the Nix language and package manager. In this benchmark we test it's performance when instantiating the hello package from nix. Note that at the time tvix does not have its own store implementation yet and it has to execute nix-store whenever it needs to copy files to the store.
