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
