In order to run the benchmarks, you +should normally execute a command such as the following: + +run-all-tests --server=mysql --cmp=mysql,pg,solid --user=test --password=test --log + +This means that you want to run the benchmarks with MySQL. The +limits should be taken from all of MySQL, PostgreSQL, and Solid. +The login name and password for connecting to the server both are +``test''. The result should be saved as a RUN file in the output +directory. + +When run-all-tests has finished, will have the individual results and the +the total RUN- file in the output directory. + +If you want to look at some old results, use the compare-results script. +For example: + +compare-results --dir=Results --cmp=mysql,pg,solid +compare-results --dir=Results --cmp=mysql,pg,solid --relative + +compare-results --dir=Results --cmp=msql,mysql,pg,solid +compare-results --dir=Results --cmp=msql,mysql,pg,solid --relative + +compare-results --dir=Results --server=mysql --same-server --cmp=mysql,pg,solid + +Some of the files in the benchmark directory are: + +File Description + +Data/ATIS Contains data for 29 related tables used in the ATIS tests. +Data/Wisconsin Contains data for the Wisconsin benchmark. +Results Contains old benchmark results. +Makefile.am Automake Makefile +README This file. +test-ATIS.sh Creation of 29 tables and a lot of selects on them. +test-connect.sh Test how fast a connection to the server is. +test-create.sh Test how fast a table is created. +test-insert.sh Test create and fill of a table. +test-wisconsin.sh A port of the PostgreSQL version of this benchmark. +run-all-tests Use this to run all tests. When all tests are run, + use the --log and --use-old options to get a RUN-file. +compare-results Generates a comparison table from different RUN files. +server-cfg Contains the limits and functions for all supported + SQL servers. If you want to add a new server, this + should be the only file that neads to be changed. + + +Most of the tests should use portable SQL to make it possible to +compare different databases. Sometimes SQL extensions can make things +a lot faster. In this case the test may use the extensions if the --fast +option is used. + +Useful options to all test-scripts (and run-all-tests): + +--host=# Hostname for MySQL server (default: localhost) +--db=# Database to use (default: test) +--fast Allow use of any non-standard SQL extension to + get things done faster. +--lock-tables Use table locking to get more speed. + +From a text at http://www.mgt.ncu.edu.tw/CSIM/Paper/sixth/11.html: + +The Wisconsin Benchmark + +The Wisconsin Benchmark described in [Bitton, DeWitt, and Turbyfill +1983] [Boral and DeWitt 1984] [Bitton and Turbyfill 1985] [Bitton and +Turbyfill 1988], and [DeWitt 1993] is the first effort to +systematically measure and compare the performance of relational +database systems with database machines. The benchmark is a +single-user and single-factor experiment using a synthetic database +and a controlled workload. It measures the query optimization +performance of database systems with 32 query types to exercise the +components of the proposed systems. The query suites include +selection, join, projection, aggregate, and simple update queries. + +The test database consists of four generic relations. The tenk +relation is the key table and most used. Two data types of small +integer numbers and character strings are utilized. Data values are +uniformly distributed. The primary metric is the query elapsed +time. The main criticisms of the benchmark include the nature of +single-user workload, the simplistic database structure, and the +unrealistic query tests. A number of efforts have been made to extend +the benchmark to incorporate the multi-user test. However, they do +not receive the same acceptance as the original Wisconsin benchmark +except an extension work called the AS3AP benchmark. |
