IBM SWG and STG Are Teaming on Software Optimization
(Project Mason)
Targeted whole-stack performance analysis and remediation
of key software
– Deep analysis & tuning across full sw stacks
– Focus on the POWER7 / POWER7+ / POWER8
– Distinguish the Power architecture as a preferred platform for
software deployment
– Focus on scalability

Extensive collaboration across SWG and STG, leveraging
and propagating skills

Focused on realistic workloads run in customer-typical
configurations, to ensure that recognized value is delivered

Deliver out-of-the-box performance where possible,
minimizing reliance on customer tuning

Drive changes to field releases as soon as practical

The WebSphere Application Server Is Optimized
For Power Systems
WebSphere Reduced code path length when running on POWER
Application Optimized to reduce the amount of lock contention on POWER
Server Access to AIX environment parameters

Java Virtual Uses 64K pages by default on AIX
Machine Elimination of unneeded exit tests in the Just-In-Time (JIT) compiler

Operating Caching optimizations in AIX to improve performance when lock
System contention is occurring in WebSphere

POWER WebSphere takes advantage of the increased number of hardware
Hardware threads available in Power Systems

Notes:
• WebSphere Application Server optimizations in Fix Pack 9 (7.0.0.9)
• JVM optimizations available with WAS Fix Pack 9 as a separate download
• AIX V6.1 optimizations (Technology Level 5)

DB2 Exploitation of Power Systems
Performance of POWER7 and DB2
– More cores and threads – 32 chips, 8 cores/chip, 4 threads/core
- Multi-year TPC-C, TPC-H and SAP benchmark leadership
-Exploited by DB2 better than any other DBMS yielding up to 30-35% performance for certain
workloads
-DB2 threaded engine built to scale on large multi core servers
– Cache exploitation
- Judicious use of L2 cache prefetch instruction embedded into DB2 to limit cache stalls
- Careful placement of hot and critical structures along processor cache line boundaries

Consolidation of DB2 on POWER7
– PowerVM virtualization second to none
- Active Memory Sharing exploited by DB2 self tuning memory manager
When peak demand hits, DB2 can immediately leverage additional resources
- Workload management integrated between AIX and DB2
DB2 able to meet customers SLAs more easily
DB2 engine
source code is
Reliability of Power Systems and DB2 compiled on AIX with its
– Power 3x – 4x more reliable than Linux on x86 optimized compiler
– 99.997% availability with Power and AIX
DB2 tightly integrated with PowerHA and other HA features of AIX

DB2 Memory Optimization Through Threading

• AIX threading greatly simplifies DB2’s memory model
• one big flat address space
• lower memory footprint
• No separate agent private memory
• Automated allocation where most needed

volume reduction with DB2 deep compression nearly 40 years
of partnership
A number of customers saved up to 30% over
Oracle for SAP database administration

Coca Cola moves from Oracle to DB2 on Power Projected 5 year savings of $750k
Systems to improve performance, scalability,
Realized 40% reduction in database size
and efficiency of its SAP environment
Better performance – up to 65% faster
Reduced workload for IT staff

COST REDUCTIONS based on actual customer case studies. See “IBM DB2: Optimized for SAP software”. All client examples cited or described are presented as illustrations of the manner in which some
clients have used IBM products and the results they may have achieved. Actual environmental costs and performance characteristics will vary depending on individual client configurations and conditions.
