the speed is decreasing when using Bubletea with go func to triger out looping main in BubleTea tui Golang

[t101804]

func (b *Bubble) Init() tea.Cmd {
	go func() {
		pool := itogami.NewPoolWithFunc(uint64(b.Data.Thread), func(i uint32) {
			b.mainScrapInit(b.Data.Weblist[i])
			defer b.wg.Done()
		})

		for i := uint32(0); i < uint32(len(b.Data.Weblist)); i++ {
			b.wg.Add(1)
			pool.Invoke(i)
		}
		b.wg.Wait()
		close(channelMsg)
	}()
	return tea.Batch(doneTick(), func() tea.Msg { return Channel{<-channelMsg, channelMsg} })
}
