Those benchmarks are wrong and misleading. Tvix contributor (but mostly reviewer I would say) here. We still don't have finished the integration with our own store, using the Nix store forces us to be slower than Nix, therefore the claims are bogus alas.

Tvix can *evaluate* a serious (?) chunk of Nixpkgs, but we have strictness bugs in some areas.

Tvix has no builder yet.

Well, congrats to y'all on good progress with the evaluator, then! That's definitely still worth celebrating. :)
