Temenos, the banking software firm, said its T24 R12 system clocked up 11,500 transactions per second at peak levels, part of record-breaking results it said were revealed in recent tests carried out in September at Microsoft’s offices in Redmond, Washington.

The tests measured the high-end performance and scalability of T24 R12 on a pre-release version of Microsoft SQL Server 2012, Temenos said in a statement.

The standardised benchmark reflected tier 1 retail banking activity volumes of 25 million accounts, 15 million customers across 2,000 branches. As part of the testing, Temenos and Microsoft sought to get the best possible connection between T24 and SQL Server 2012 to show the latest features of both the application and the pre-release version of SQL Server.

The system processed an average of more than 10,000 interest accrual and capitalisations per second during close-of-business testing; in all, it handled 25 million capitalisations and account accruals in less than 42 minutes.

“These performance results, achieved on the pre-release version of SQL Server 2012, preview the power that will be available when SQL Server 2012 is released,” said Joe Pagano, worldwide managing director, banking and capital markets at Microsoft.
