We have a large team working on this issue and progress is being made already. Allan Packer is leading the team that is working on this and his blog (http://blogs.sun.com/allanp/) sometimes has information on the performance project. One of the videos he references talk about the future of the performance project at Sun. (http://link.brightcove.com/services/player/bcpid1683878780?bctid=1892187731) It should be noted that improving performance of an application is a long term effort. Performance gains come in small doses typically and this project is one that might take some time. Given that, there are other people at Sun that are trying to figure out ways MySQL can be used on larger systems (like the T5440). The thought is around horizontally scalability within a system-- either using virtualization or not. This article by Benoit was simply one example of these efforts. I understand the concerns with this approach (losing the system causes loss of multiple databases), but there advantages (like cost savings, energy savings, consolidaton, etc.) that play a part as well. I'd be interested in hearing more of your thoughts on horizontally scaling within a system.

When I saw this initially I thought that is what they had done (scale one instance). Maybe someone in Sun is working on that. Keith yeah..my thoughts exactly.

He's interested in testing the ndbmtd and/or several ndbd nodes together on that system as well. Hey Stewart, I spoke to Benoit at the CEC last week.
