Not to rehash an old argument, but I am watching a recent video on performance work being done by Sun hosted by Allan Packer (a recorded MySQL University session) and one of his bullet points was “Scale out when it makes sense, rather than just because there is no alternative”. That is what they are working on in his group at Sun.
You mean I will be able to buy 8 and 16 cores boxes and be able to use all the cores?
Hallelujah and Amen brother 
Allan, thanks to you and all other who are working on this both inside and outside Sun.
