Data Explosion and the need for open source
•90% of the worlds data was created in the last two years
•Majority is ‘unstructured’
•Oracle dominate RDBMS
•PostgreSQL is the fastest growing open source database

Open Source is the future
• All organisations are looking to cut costs - Database infrastructure is #1
• Open source technologies deliver substantial cost savings
• EnterpriseDB have made PostgreSQL Enterprise ready and delivered Oracle compatibility
• 80% savings on licensing - is x86 the best hardware platform ?
• Proof of concept - performance benchmarking

Linux Performance on Power
• Power7+ CPU Platform has huge potential - CISC vs. RISC
• Especially for large multi-threaded workloads
• But - development effort is still focussed on x86
• Don’t expect best performance out of the box
• Tune. Tune. Tune.

Case Study - PostgreSQL
• PostgreSQL 9.2.4
• Big performance improvements over 9.1 and earlier
• Especially multi-user workloads
• Two types of benchmark
• pgbench SELECT - simple reporting query benchmark
• HammerDB - based on industry standard TPC-C benchmark simulating OLTP workloads
• Reference system IBM X3650 M4 - 2 x Xeon E5-2680 - 16 core, 512GB RAM
• Equivalently priced x86 tin

pgbench - Step 1 - “Out of the box”
• Compiled from source
• Default toolchain
• Factory configuration on hardware
• Power7 = 31% more TPS than x86 !
31%

But.. we can do better
• All tuning work undertaken in house at Quru
• No source code changes
• Under the guidance of IBM Raleigh / Montpellier
• We managed to beat their results !

pgbench - Step 2 - “Tuned”
• 2 months testing and tuning
• Re-compiled code
• Hardware performance tuned
• Kernel performance tuned
• Application binaries profiled
99%
52%
31%

HammerDB - TPC-C Benchmarks
• Tuning gives PowerLinux competitive advantage
• Power7 = 58% more NOPM than x86 !
58%

Quru tuning unlocks the performance of PowerLinux
• SPEC CPU2006
• Publicly available at http://www.spec.org
• “Base” figures are untuned - strict guidelines
• “Peak” figures are tuned - freedom for tuning allowed

Conclusions
• Quru achieved a significant uplift in performance
• Every environment is unique so tuning is essential
• Our integrated solution is the future of Oracle cost containment in the enterprise

• Two whitepapers to follow and an event 10th December at IBM Southbank
