Hi Charles: When you state "Wouldn't actual measurements on production hardware be more interesting? ...", do you mean end-user system applications including low level disk performance. I am not up to speed as to the current type of enterprise disk storage system controls (i.e. raid etc.)are used but I would think overall hardware and system integration would be a better measure of performance rather than just processor speed. What's your understanding of symmetrical multithreading? This is controlled by the type of OS isn't it? SOLARIS performs this type of processing where several different computing tasks can work their way through a single pipeline at the same time. As a result all the various low level system controls like storage are efficiently managed by the OS and processor (speed). Therefore, the best measurement of hardware and system performance is not just processor speed but rather how the OS and processor work together to manage the symmetrical multithreading tasks. These tasks will vary based on the type of application(s) used; a database record read and write vs a computation that requires floating point functions or heavy computations that render video graphic pixels. Does the Itanium provide symmetrical multithreading? If so, can I assume that currently Microsoft OS does not allow symmetrical multithreading? Perhaps you can enlighten me and the board on how symmetrical multithreading works with SUNW's Sparc processor and Solaris OS vs the WinIntel product. It's my observation that SUNW has optimized their processor and OS (in combination) to provide a very efficient server platform. The proposed Intel product is just part of the solution for a powerful new server processor but it has yet to be fine tuned with a robust OS (Windows, LINUX, SOLARIS, UNIX). Until this is accomplished, the relative stated performance gains of the Intel processor are mute IMO. EKS
