The MySQL benchmarks Ver $benchmark_version

All benchmarks takes the following options:

--bzr-repo=<DIR>
  Specifies a bazaar repository directory for the test suite to obtain the 
  repo version which it then uses as part of the results output filenames 

--comments
  Add a comment to the benchmark output.  Comments should contain
  extra information that 'uname -a' doesn\'t give and if the database was
  stared with some specific, non default, options.

--cmp=server[,server...]
  Run the test with limits from the given servers.  If you run all servers
  with the same --cmp, you will get a test that is comparable between
  the different sql servers.

--create-options=#
  Extra argument to all create statements.  If you for example want to
  create all MySQL tables as InnoDB tables use:
  --create-options=ENGINE=InnoDB

--database (Default $opt_database)
  In which database the test tables are created.

--debug
  This is a test specific option that is only used when debugging a test.
  Print out debugging information.

--dir (Default $opt_dir)
  Option to 'run-all-tests' to where the test results should be stored.

--fast
  Allow the database to use non standard ANSI SQL commands to make the
  test go faster.

--fast-insert
  Use "insert into table_name values(...)" instead of
  "insert into table_name (....) values(...)"
  If the database supports it, some tests uses multiple value lists.

--field-count
  This is a test specific option that is only used when debugging a test.
  This usually means how many fields there should be in the test table.

--force
  This is a test specific option that is only used when debugging a test.
  Continue the test even if there is some error.
  Delete tables before creating new ones.

--groups (Default $opt_groups)
  This is a test specific option that is only used when debugging a test.
  This usually means how many different groups there should be in the test.

--lock-tables
  Allow the database to use table locking to get more speed.

--log
  Option to 'run-all-tests' to save the result to the '--dir' directory.

--loop-count (Default $opt_loop_count)
  This is a test specific option that is only used when debugging a test.
  This usually means how many times times each test loop is executed.

--help
  Shows this help

--host='host name' (Default $opt_host)
  Host name where the database server is located.

--machine="machine or os_name"
  The machine/os name that is added to the benchmark output filename.
  The default is the OS name + version.

--odbc
  Use the ODBC DBI driver to connect to the database.

--only-missing-tests
  Only run test that don\'t have an old test result.
  This is useful when you want to do a re-run of tests that failed in last run.

--optimization='some comments'
 Add coments about optimization of DBMS, which was done before the test.

--password='password'
  Password for the current user.

--socket='socket'
  If the database supports connecting through a Unix socket,
  then use this socket to connect

--regions
  This is a test specific option that is only used when debugging a test.
  This usually means how AND levels should be tested.

--old-headers
  Get the old benchmark headers from the old RUN- file.

--server='server name'  (Default $opt_server)
  Run the test on the given SQL server.
  Known servers names are: Access, Adabas, AdabasD, Empress, Oracle,
  Informix, DB2, mSQL, MS-SQL, MySQL, Pg, Solid and Sybase

--silent
  Don't print info about the server when starting test.

--skip-delete
  This is a test specific option that is only used when debugging a test.
  This will keep the test tables after the test is run.

--skip-test=test1[,test2,...]
  For run-all-programs;  Don\'t execute the named tests.

--small-test
  This runs some tests with smaller limits to get a faster test.
  Can be used if you just want to verify that the database works, but
  don't have time to run a full test.

--small-tables
  This runs some tests that generate big tables with fewer rows.
  This can be used with databases that can\'t handle that many rows
  because of pre-sized partitions.

--suffix (Default $opt_suffix)
  The suffix that is added to the database name in the benchmark output
  filename.  This can be used to run the benchmark multiple times with
  different server options without overwritten old files.
  When using --fast the suffix is automaticly set to '_fast'.

--random
  Inform test suite that we are generate random inital values for sequence of
  test executions. It should be used for imitation of real conditions.

--threads=# (Default 5)
  Number of threads for multi-user benchmarks.

--tcpip
  Inform test suite that we are using TCP/IP to connect to the server. In
  this case we can\t do many new connections in a row as we in this case may
  fill the TCP/IP stack

--time-limit (Default $opt_time_limit)
  How long a test loop is allowed to take, in seconds, before the end result
  is 'estimated'.

--use-old-results
  Option to 'run-all-tests' to use the old results from the  '--dir' directory
  instead of running the tests.

--user='user_name'
  User name to log into the SQL server.

--verbose
  This is a test specific option that is only used when debugging a test.
  Print more information about what is going on.

--hw='some comments'
 Add coments about hardware used for this test.

--connect-options='some connect options'
  Add options, which uses at DBI connect.
  For example --connect-options=mysql_read_default_file=/etc/my.cnf.
