Boost performance for mission-critical SAP applications.

The following features enable sustained high performance of SAP landscapes:

Page Cache Management
The page cache limit is a kernel parameter that has been added into SUSE Linux Enterprise Server for SAP Applications. Many SAP applications are designed to use large amounts of memory for optimal performance. The Linux kernel pages out rarely-accessed memory for filesystem performance. These optimizations conflict causing SAP application performance to slow down, and if the application is built on Java the “garbage collection” process makes it even worse. SUSE has developed Page Cache Management exclusively for SUSE Linux Enterprise Server for SAP Applications to give you control of page caching.

The page cache limit feature of SUSE Linux Enterprise Server limits the amount of page-cache used and optimizes the Linux paging behavior. This feature is crucial for SAP applications to maintain performance. See SAP Note 1557506 for more information.

Performance tuning
SUSE Linux Enterprise Server for SAP Applications includes a package that automates optimized performance tuning for SAP application and SAP HANA systems when they are configured and installed using the YaST-based installation wizard.

Dedicated update channel SAP and SUSE validated and certified the SUSE Linux Enterprise Server for SAP Applications jointly to eliminate potential software incompatibilities, and we continue to test and validate the software stack. As a result, SUSE Linux Enterprise Server for SAP Applications consistently delivers outstanding uptime and performance—even under full CPU loads and high memory stress. SUSE provides a dedicated update channel to deliver performance enhancements to the OS corresponding with updates to SAP applications.

“In general, our SAP NetWeaver Business Warehouse applications run several times faster on SUSE Linux Enterprise Server than they did on our previous UNIX platform. In some cases, we have seen performance improve by a factor of four to five. This means that business users can run the analyses they need and get insight into business data much more easily than before.”
