Customer experience with SAP BW FEMS-Pushdown

A few months ago we released a new SAP BW statement generator, which increases BW query performance for complex queries containing FEMS filters, see https://blogs.msdn.microsoft.com/saponsqlserver/2017/03/06/bw-queries-by-factors-faster-using-fems-pushdown. In the meanwhile, a few customers who tested the new feature, provided feedback to the “SAP on SQL Server development”. Based on this feedback, we further improved the performance of… Read more

Parallel Processing in SAP

New generations of CPUs do not provide any significant single-thread performance improvements. Instead, the number of logical CPU cores is increasing with each new CPU generation. You can significantly reduce the runtime of a task by running sub-tasks in parallel on many CPU cores. However, splitting a task into sub-tasks consumes additional resources (CPU and… Read more

Transparent Data Encryption (TDE) acceleration for SQL 2016 in Windows Azure

Today we want to show you the speed improvements we get by supporting the Intel AES-NI instruction set for transparent data encryption (TDE) on Windows Azure. This instruction set reduces the CPU overhead of turning on Transparent Data Encryption for SQL Server databases. For the testing scenario we used an Azure DS15 virtual machine with… Read more

Using Columnstore on ERP tables

SQL Server columnstore indexes are optimized for aggregations of large amounts of data. Therefore, they are successfully used in SAP’s data warehouse system SAP BW since years.

BW Queries by factors faster using FEMS-pushdown

Complex SAP BW queries often contain FEMS-filters. These filters used to be applied on the SAP application server, which was not very efficient. A new SQL statement generator in SAP BW implements an optimized algorithm for FEMS processing. We have seen performance improvements up-to factor 100. The actual performance improvement varies heavily for different BW… Read more
