Why are you lying? It's not quick, let alone "pretty much instant". Neither on my M3 nor on my gaming machine. Actually I think Avalonia's start-up time is the worst out of all GUI frameworks I've used so far, including Electron.
Hah, interesting. On desktop (Apple M2) it pretty much feels instant to me. When targeting embedded, sure there is a delay.
Regarding memory consumption, can't really tell. It never was at the point where we had to intervene AND we target embedded devices with some apps.
What's your benchmark?
