  • Blog Post: Kilimanjaro Ships!

    SQL Server 2008 R2 launches today! While the name “R2” sounds like an incremental update to SS2008 (or half of a Star Wars droid), in fact Kilimanjaro (the internal code name) is packed with big features. We’ve also got a lot to show for our work on performance and scalability. The four results at the...
  • Blog Post: An ETL World Record Revealed (Finally)

    We suppose a more appropriate title would have been: Better Late Than Never. David should begin by apologizing. Last month was the first anniversary of the ETL world record we set last year with SSIS, loading 1 TB of data in under 30 minutes. While Len did a nice blog post on the project at the time...
  • Blog Post: Windows Server 2008 + SQL Server 2008 = Geo-replication Benefits

    After running an experiment, using datacenters on each coast of the U.S., our friends in MSCOM ops verified that the combination of Windows Server 2008 and SQL Server 2008 are great for enabling database geo-replication, thanks to a 100X gain in performance. The experiment provided sufficient evidence...
  • Blog Post: SQL Server is Movin' On Up!

    At last week's WinHEC in Los Angeles, SQL GM Quentin Clark joined Windows Server VP Bill Laing on stage, to announce our upcoming support for more than 64 logical processors, the current limit in Windows and SQL Server. This expanded scale-up capability is planned to be released in SQL Server code named...
  • Blog Post: TPC-E – Raising the Bar in OLTP Performance

    Glenn Paulley, Director of Engineering at Sybase iAnywhere, posted a commentary titled “ The State of TPC-E ” on his blog three weeks ago (10/3/08). A better title would have been “All TPC-E Results Are On Microsoft SQL Server. Why?” Mr. Paulley takes issue with Brian Moran’s statement that “ the most...
  • Blog Post: SQL Server 2008 is on its way with great performance

    Just left the final shiproom meeting for SQL Server 2008, and am happy to say every team has signed off, so the product is now in the hands of manufacturing, and in process toward web and media availability for you. We've shipped! MSDN and TechNet subscriber downloads are now live, with more to come...
  • Blog Post: ETL World Record!

    Today at the launch of SQL Server 2008, you may have seen the references to world-record performance doing a load of data using SSIS. Microsoft and Unisys announced a record for loading data into a relational database using an Extract, Transform and Load (ETL) tool. Over 1 TB of TPC-H data was loaded...
  • Blog Post: What's swimming in your bufferpool?

    When doing a performance investigation a useful thing to do is look at what data is present in the buffer pool. This can be used to analyze impact of running a query on the state of data pages in buffer pool. By collecting the pre and post picture of buffer pool, you can see the cost of running a query...
  • Blog Post: Two handy papers on common database performance considerations

    Len posted recently the link to the new Analysis Services performance guide. If you also care about SQL Server engine performance, these two papers are worth a quick read: Troubleshooting Performance Problems in SQL Server 2005 , which takes you through steps for identifying and resolving typical...
  • Blog Post: High Volume Update Performance

    SQL Server does a great job of optimizing processing across a wide range of runtime scenarios, while also providing a flexible configuration and execution environment. One of the tradeoffs associated with this level of flexibility is that different configurations and implementations, while logically...
