SQL Server:

SQL Server 2000 running on the Windows can support up to 32 CPU and up to 64GB physical memory (RAM) on a computer!

How Fast Is Fast? SQL Server 2000 can handle 709,220 transactions per minute! SQL Server 2000 has further established its position as the fastest database in the world. With a performance rating of 709,220 transactions per minute (tpmC) and price/tpmC of $14.96 US, a 32-node Compaq ProLiant DL760-900-256P system exceeded the previous record, which was also held by SQL Server 2000.

Another benchmark test demonstrated support for 25,200 simulated concurrent users and performed CRM transactions at the rate of 2,024 business processes per minute. These results were achieved on a 24-processor Unisys ES7000 database server and yielded average response times between one and two seconds.
