ENT News | News: Itanium System Breaks 1 Million Transactions on TPC-C: "The result also widens the performance gap between scale-up Unix/Oracle and scale-up Windows/SQL on HP's own 64-processor Integrity Superdome system. HP is now getting 28 percent better performance with its own Unix operating system and Oracle's new 10G database on the system than it got with Windows Server 2003, Datacenter Edition, and SQL Server 2000, Enterprise Edition. Both the Unix and Windows software stacks used in the tests are 64-bit."
