+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.
