dominion-ecs-java VS retinazer

You are right, I will add more info about the architecture! About which operations perform better you can already relying on the available benchmarks

Check out the new Quick Start section to see the “how-to”.

Dominion aims to have a clean and minimal API surface and all the features already implemented are documented, tested, and with benchmarks. A simple example code has been provided in a dedicated module.

With this project, I aim to demonstrate that Java can also participate in the competition and for good reasons.

Dominion is still in its early stages but has already started running at a very high speed, fast by design. It's still far from a complete ECS solution, but I've already implemented the API to create/delete Entities with Components, find them and iterate. I've also posted some benchmarks related only to what I've achieved so far (so on the speed of creating, deleting, and iterating Entities), and I think it looks very promising.

The readme on Artemis's github lists some benchmarks, and though these aren't direct comparisons and only napkin math, your project seems competitive with the abandoned Retinazer which consistently outperforms it! This early in development that certainly seems like a good sign!
