The TPC-C benchmark results touted in the linked article were run on Itanium, a very different architecture from the Intel architecture that the vast majority of Linux applications run on. Itanium was designed from the ground up for server performance, the results you get on it will not translate well to Intel or AMD systems.
The vast majority of the Itanium systems sold are HP boxes running HPUX or VMS or Tru64. Dell was selling Itanium Linux and Windows systems but they only sold a very few, so they gave up. SGI was selling them too, and we all know what happened to them.
Again, if these benchmark numbers meant anything, everyone would have rushed out and bought a nifty new Itanium machine. The only ones I ever see are in our lab.
