ENT News | News: SQL Server's Scalability Run Stalls "SQL Server 2000 64-bit and Windows Server 2003 Datacenter Edition 64-bit had a great run, but it looks like Microsoft's challenge to Unix and Oracle on scalability is over for now.
Ever since the April launch of Windows Server 2003, every major benchmark run by Windows Server 2003 Datacenter Edition and SQL Server 2000 64-bit set a new record for raw performance.
Still, Microsoft's run at the top has been far from a waste. In the past, Microsoft's best efforts for non-clustered scalability petered out with Microsoft somewhere in the range of 25 percent to 50 percent of the top-end scalability of the highest-end systems. No longer. This time SQL Server and Windows Datacenter appear to have topped out at 95 percent of the raw-performance capacity of the top systems -- way beyond the real-world requirements of even the most demanding systems."
