Itanium has been on the market for about 18 months now (counting from Merced). Regular folks using the most recent generally available compilers do not see the performance hoped for (other than floating point). Saying Eugene can make it run fast is like saying, well Hsu could build a faster hardware engine today...what about for the rest of us? Bob, do you even have an Itanium system? It sounds like no. I have to think if it was such a good thing, you would have found some $$$ for one.
