Ingres just published a TPC-H benchmark for VectorWise, an analytic database technology employing 1) SIMD processing (Intel SSE 4.2), 2) better memory optimizations to leverage on-chip cache, 3) compression, 4) Column-based storage.
Ingres originated as a research project at UC Berkeley (see Wikipedia) in the 1970s, and has since become a commercially supported, open source database system. Apparently, Ingres project people later founded Sybase. So Ingres in a sense, is the grandfather (or perhap grand-step-uncle?) to SQL Server. According to the Ingres whitepaper, VectorWise spun off from CWI in Amstersdam, with some roots in MonetDB? For the time being, Ingres VectorWise is not open-source. The interesting aspect of VectorWise among other column store database products is use of the SIMD, as in utilizing the special instructions and registers built into recent generation microprocessors. (In a previous blog, I proposed special SIMD instructions to improve the efficiency on accessing pages in traditional row-storage database engines.)
Below are TPC-H results at scale factor 100GB on HP ProLiant DL380 G7 with two Xeon 5680 six-core 3.33GHz processors for SQL Server 2008 R2 and Ingres VectorWise 1.5.
Overall, the VectorWise columnar database has about 2.5X higher score on Power, and 5X on Throughput. The glaring weak point of SQL Server is that the throughput is (almost 2X) lower than the power. The SQL Server parallel execution engine is very powerful running a single stream with no other concurrent queries competing for CPU. It does not have a good strategy for sharing compute resources with other concurrent long running queries.
The general expectation set by all the new technology, columnar storage, memory optimization and vector processing was 10X, not 3X. However, we should consider that the TPC-H benchmark score is a composite geometric mean of 22 individual queries. The individual query performance differences between SQL Server and VectorWise are shown below, on a logarithmic scale (base 2, not 10, a cool feature in Excel 2007?).

PBS Software announces PBS Nearline Storage solution with Actian Vectorwise
PBS Software GmbH and Actian Corporation today announced their newly formed agreement to bring the power of Actian’s record-breaking analytic database, Vectorwise, to PBS nearline storage solutions.
A pioneer in using column-based database technology to enable Information Lifecycle Management in SAP environments, PBS Software offers nearline storage solutions for SAP Business Warehouse (BW) and ERP installations. PBS solutions help SAP users to process large and complex data volumes by compressing and storing lesser-used data sets in column-based database architectures in order to free up SAP applications considerably. Thanks to column-based database technology, users have fast access to nearline stored data in order to conduct adhoc analyses. Working with Actian, PBS nearline storage solutions are now also available by using Actian Vectorwise as the column-based database server.
Agreement marks the launch of bundled solution for analysing large databases at a lower cost
Actian Corporation has signed a partnership agreement with Numsight, a French computer software and systems consultancy which provides hosted marketing database solutions to support data analytics in the retail sector. Covering technology solutions and marketing efforts, the agreement marks both companies’ commitment to provide customers with data analytics at the speed of thought.
