This is the result file of the different benchmark tests.

The number in () after each tests shows how many SQL commands the particular
test did.  As one test may have many different parameters this gives only
a rough picture of what was done.  Check the source for more information :)

Keep in mind that one can\'t compare benchmarks run with different --cmp
options. The --cmp options sets the all limits according to the worst
limit for all server in the benchmark.

Numbers marked with '+' are estimated according to previous runs because
the query took longer than a given time-limit to finish. The estimation
shouldn\'t be far from the real result thought.

Numbers marked with '?' contains results that gave wrong result. This can only
be used as an indication of how long it took for the server to produce a wrong
result :)

Numbers marked with '*' are tests that was run a different number times
than the test in the first column.  The reason for this is normally that the
marked test was run with different options that affects the number of tests
or that the test was from another version of the MySQL benchmarks.

Hope this will give you some idea how each db is performing at what thing ....
Hope you like it .... Luuk & Monty (1997)

$0  Ver 1.2

This program parses all RUN files from old 'run-all-tests --log' scripts
and makes a nice comparable table.

$0 takes currently the following options:

--help or --Information		
  Shows this help

--cmp=server,server,server (Default $opt_cmp)
Compares all runs that are done with the same --cmp options to run-all-tests.
The most normal options are '--cmp=mysql,pg,solid' and '--cmp ""'

--dir=...  (Default $opt_dir)
From which directory one should get the runs.  All runs made by
run-all-tests --log is saved in the 'output' directory.
In the 'results' directory you may have some example runs from different
databases.

--html
  Print the table in html format.

--machine='full-machine-name' (Default $opt_machine)
Use only runs that match this machine.

--relative
Show all numbers in times of the first server where the time for the
first server is 1.0

--same-server
Compare all runs for --server=....  The --machine is not used in this case
This is nice to compare how the same server runs on different machines.

--server='server name'  (Default $opt_server)
Put this server in the first result column.

--skip-count
Do not write the number of tests after the test-name.

--verbose
Write the number of tests in each column. This is useful when some column
is marked with '*'.
