Incremental compile times were quite fast, I'd say in the 1-2 seconds. I also have another project where I'm using Dioxus-web for a web application. When building a web app, it also has hot code reloading and I'd say reloads take under a second (though I just started this app so it only has a couple hundred lines of code).

I have an M1 Pro Max though, which is quite a fast machine.
