The MySQL Benchmarks
|
||
|
|
|
||
|
|
These tests require a MySQL version of at least 3.20.28 or 3.21.10.
|
||
|
|
|
||
|
|
Currently the following servers are supported:
|
||
|
|
MySQL 3.20 and 3.21, PostgreSQL 6.#, mSQL 2.# and Solid Server 2.2
|
||
|
|
|
||
|
|
The benchmark directory contains the query files and raw data files used to
|
||
|
|
populate the MySQL benchmark tables. 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.

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.
