wire command takes too long to execute

[Lykr]

We are building a simple service with wire. The code looks like following:

func InitializeApp() *App {
	wire.Build(
		NewApp,
		service.NewA,
		service.NewB,
		service.NewC,
		service.NewD,
		dal.NewDal,
	)
	return &App{}
}

It takes about 80s to get following output:

func InitializeApp() *App {
	b := service.NewB()
	dal := dal.NewDal()
	d := service.NewD(dal)
	a := service.NewA(b, d)
	c := service.NewC(d)
	app := NewApp(a, b, c)
	return app
}

Why does it take so long to execute the command?
