Super Smack is a benchmarking, stress testing, and load generation tool for MySQL. It is similar to the Apache bench tool. It is currently available for a limited set of Linux and Unix platforms. Super Smack can be found at http://vegan.net/tony/supersmack/. mybench is a simple customizable benchmarking framework for MySQL. It is written in Perl and can be found at http://jeremy.zawodny.com/mysql/mybench/.

Tip For best results, you should disable the MySQL query cache before running benchmarks. You can turn off the query cache by issuing the command SET GLOBALS query_cache_size = 0; in the MySQL client interface. This will allow your benchmarks to record the actual time of the queries rather than the time the system takes to retrieve the query from the cache. You ll get a more accurate reading of the performance of your system.

If the base set of benchmarks is all that you need, you can run the command perl run-alltests --small-test and generate the results for the basic set of tests. While running all of the tests ensures a more thorough measurement of the performance, it can also take a long time to complete. If on the other hand you identify a particular portion of the system you want to measure, you can run an individual test by executing the test independently. For example, to test the connection to the server, you can run the command perl test-connect. Table 4-3 lists a few of the independent tests available for you to run.

Note The benchmarking suite runs the tests in a single thread. MySQL AB has plans to add multithreaded
tests to the benchmark suite in the future.

For more information about other forms of benchmarking available for MySQL, see Michael Kruckenberg and Jay Pipes s Pro MySQL.8 It is an excellent reference for all things MySQL.
Running the Small Tests
Let s examine what you can expect when you run the benchmarking tools on your system. In this example, I ran the benchmarking suite using the small tests on my Windows system. Listing 4-5 shows the top portion of the output file generated. Listing 4-5.

At the top of the listing the benchmarking suite gives the metadata describing the tests run including the date the tests were run, the version of the operating system, the version of the server, and any special optimization or hardware installed (in this case, none). Take a look at what follows the metadata. You see the results of each of the tests run reporting the wallclock elapsed seconds. The times indicated in the parentheses are the times recorded during the execution of the benchmark suite itself and should be deducted from the actual wallclock seconds for accurate times. Don t be too concerned about this as this section is mostly used for a brief look at the tests in groups. The next section is the most interesting of all as it contains the actual data collected during each test. The results of the example benchmark tests are shown in Table 4-4. I have omitted some of the rows to save space.
