In conclusion I can not say that I am impressed by any speed improvements. Looking at the values one can see no speed gain on my PPC machine. Things should be different for Intel Mac users. Being a universal binary this app should provide them with some significant speed improvement. The only thing that offers a slight improvement is launch. The rest I can live without, for now.
