Is there a way to imrpove startup speed in packed electron app?

[wthks]

When I build my electron app with single file, the electron app takes about 10 seconds to start the splash screen. however when I start the app from the win_unpacked folder the splashscreen shows in 1,2 seconds.

Is there any way to make that faster? I think the electron app first unpacks the files and then starts the app..
