Ubuntu, Kubuntu, Xubuntu Sources close to Canonical and IBM are telling me that Ubuntu may soon be certified on IBM's System p mini-computers and blades and System z mainframes.

Why run Linux on a slow Mainframe?

Mainframe cpus are much much slower than x86 cpus. Any decent Quad core x86 cpu is much faster than the newest and fastest Mainframe cpu. So why would anyone want to run Linux on slow extremely expensive hardware?

Look at dhrystone mips, and compare the latest and fastest z196 Mainframe cpu vs Quad Core i7: 50.000 MIPS vs 160.000MIPS
