For a while, during the development of 23.1, the new font backend was really slow on Windows, but currently it is not so (or, at least, we don't receive many complaints about its speed); though it's true that it is slower than 22.X; it's the price to pay for much better font support. If you find it unbearably slow I'd suggest filing a bug in the Emacs bug tracker, giving as much relevant information as possible (for example, fonts used, etc.). Juanma
