The performance improved but the reason why I advice `--gc:orc` now is that it's the complete solution, all your dependencies will work with it (assuming the dep has been ported to orc to begin with) so that we avoid ecosystem splits. To avoid Orc's overhead for your own code use the `.acyclic` (and `.cursor`) annotations.
