here’s a page with a very unscientific benchmark that runs a computed signal for every pixel of a {320p, 480p, 720p, 1080p, 4k} canvas and tries to recompute 10% of the graph per frame. on my m4 macbook pro, dalien-signals manages the highest fps and lowest heap out of libraries i could find to test. i think there’s still room for improvement though, im not satisfied with cache locality of graph under heavy churn; iirc i only compact/move stuff on resize or a large deallocation batch. so theres potential for original js-heap-allocated alien-signals to be faster in spots where moving GC becomes an advantage. lemme know if my library ends up being a win for you!
