Yes, Solid is very fast, but Svelte's Signals implementation seems to be even more performant. [0]

I just loved the simplicity of using $: for deriveds and effects in Svelte 3 and 4. But after building a correlation matrix [1] and a work project with Svelte 5, I have to say that I really like it.

To be fair by that metric Vue has the fastest now with its core built with Alien Signals. Raw reactivity benchmarks don't actually show very much because these systems are so fast that the quickest to the slowest reactive library doesn't even make a dent on a test that says render the DOM. And I say this as a benchmark enthusiast (and as that benchmark actually was crated by Milo from the SolidJS core team as part of our 2.0 research)

That's good to know, thanks! Alien Signals is such a great name.

Thanks for the info. I’ll definitely check Svelte 5 out.
