3 CPU Performance Why measure CPU Performance? CPU performance has a huge impact on - performance of most database operations - Oracle license (core factor) and maintenance cost - even with Unlimited License Agreement (ULA) copyright 2013 by benchware.ch slide 3

4 CPU Performance What is measured? CPU performance from the Oracle point of view - Pure processor performance - Including level 1, 2, 3 cache - No memory access - No I/O operations Speed of single thread - Elapsed time [s] for algorithms - Operations per second [ops] Maximum throughput of system - Operations per second [ops] Scalability - Throughput per process for n = {1, 2, 4, 8,, n} Efficiency of - Multi threading - Virtualization - Encryption copyright 2013 by benchware.ch slide 4

5 CPU Performance How is CPU Performance measured? Following data types are most important for Oracle applications - PLS_INTEGER - NUMBER (no direct mapping to hardware data type) - VARCHAR2 - DATE Benchware uses Oracle data types in PL/SQL to measure the performance characteristics of a CPU - PL/SQL is the most powerful transaction programming language - Some important core applications are completely written in PL/SQL copyright 2013 by benchware.ch slide 5

6 CPU Performance Overview of CPU performance tests with Test Codes Oracle CPU Performance Test Code for SIMPLE_ INTEGER Test Code for SIMPLE_ FLOAT Test Code for PLS_INTEGER Test Code for NUMBER Test Code for Basic numeric operations CPU-11 CPU-12 CPU-13 CPU-14 - VARCHAR2 Oracle CPU Performance Mixed operations with SQL built in functions Test Code for SIMPLE_ INTEGER Test Code for SIMPLE_ FLOAT Test Code for PLS_INTEGER Test Code for NUMBER Test Code for VARCHAR2 - CPU-22 CPU-23 CPU-24 CPU-25 Oracle CPU Performance Fibonacci numbers n = {39, 40, 41, 42} Prime numbers [ , ] Test Code for SIMPLE_ INTEGER Test Code for SIMPLE_ FLOAT Test Code for PLS_INTEGER Test Code for NUMBER Test Code for VARCHAR CPU CPU-44 - Remarks: All CPU performance tests are using level 1, 2, 3 CPU cache and are therefore CPU bound. The Benchware Performance Suite uses optional encrypted tablespace to test the impact of encryption to performance. copyright 2013 by benchware.ch slide 6

7 CPU Performance Remarks on other benchmark tools... SAP, TPC, Swingbench, Hammerora, - No specific CPU performance tests for Oracle database operations with Oracle data types, e.g. with data type NUMBER, VARCHAR2, DATE SPEC, CPUbench, - No specific CPU performance tests for Oracle database operations with Oracle data types, e.g. with data type NUMBER, VARCHAR2, DATE Remarks: Application developers appreciate the very unique characteristics of the Oracle numeric data type NUMBER, therefore most Oracle applications use this data type as their standard numerical data type. The data type NUMBER uses a binary coded decimal implementation. This method can not be directly mapped to hardware data types and causes a lot of overhead. The performance of arithmetic operations with the data type NUMBER is therefore by factors slower than native data types like SIMPLE_INTEGER. Oracle implemented a specific software library for each processor architecture to handle numeric operations with the data type NUMBER. During our benchmarks, we experienced that the performance of the data type NUMBER does not correlate with industry standard SPEC benchmark results. copyright 2013 by benchware.ch slide 7

This value does not correlate with SPECint_base2006 copyright 2013 by benchware.ch slide 9
