Slow TimeLine

Yesterday I had the 1.7.1, The timeline was Fast, When opening My Minecraft Windows 10 It took 12 Seconds.When Entering a Server, Enter a New World or Put on a texture

 The Timeline is the loading time

When updating to 1.8.0 (I have the Minecraft Windows 10 Bought) The Timeline was slower to get texture, enter a world or a server
It took 20 seconds or the game is locked

I do not know if this happens in Minecraft Pocket Edition
