##### 3. The number of iterations for each test can be modified in the test itself (e.g., in test/Performance/benchmark/sqlsrv/SqlsrvSelectVersionBench.php). Each bench class in a test, or the parent class that it extends from, has a @Iteration(n) annotation. If you change the number in this annotation, you will change the number of iterations run for this test. By default, most tests are set to 1000 iterations.
On Linux and Mac, the script must be executed with `sudo python3` because to enable pooling it needs to modify odbcinst.ini system file. As an improvement, the location of the odbcinst.ini file can be changed so that sudo is not required.
`-platform` - The platform that the tests are ran on. Must be one of the following: Windows10, WindowsServer2016, WindowsServer2012, Ubuntu16, RedHat7, SUSE12, Sierra.
`-testname` (optional) - The test to run. Must be the file name (not including path) of one test or 'all'. Default is 'all'. If one test is specified, must also specify the -php-driver option to sqlsrv or pdo_sqlsrv.
