While this is not SuperNative desktop, and I do not have access to the codebase, I'd expect it to be similar to Swift in here, maybe slightly worse/better. This is myself for fun porting ZXN Studio to Swift, also to hopefully increase speed of porting to SuperNative desktop. So when it comes out I'd expect ZXN Studio to meaningfully improve performance from it's electron version.
Launch may be slightly slower (since Laravel + PHP has to start up I presume). Again this is all speculation, just myself burning tokens for experimenting
