I had a pleasure to work with my colleagues from Oracle – Radosław Kut and Krzysztof Marciniak – at comparing the performance of In-Memory queries between Sparc M7, Intel® Xeon® X5670 and Intel® Xeon® E5-2699.
You can find results of our findings in this presentation: https://www.oracle.com/webfolder/s/delivery_production/docs/FY16h1/doc17/DB12c-on-SPARC-M7.pdf
Following their methodology I’d like to present appropriate results from P8 tests.
(Please get familiar with the presentation first)
Well, it looks a little bit messy and unstable, but things got better after setting this parameter:
export LDR_CNTRL=DATAPSIZE=64K@TEXTPSIZE=64K@STACKPSIZE=64K oracle
(Many thanks to Radoslaw Mankowski from IBM for this hint)
The last step which you can see on this chart is for 100 users.
Make your own conclusions 😉
Special thanks to Adam Boliński for helping to setup the AIX environment and Sławomir Wolak for making P8 tests possible.
