Performance Testing Script

By Jesse McLain,

This script helps developers test the performance of a stored procedure or block of code. Although it was written specifically to assist me in comparing stored procedures, it can easily be modified for other testing purposes.

The script expects two tables, 'Seq1' and 'Seq2' to exist, and be of the structure as listed in the header comment of the script. It will test the code of interest by running it using different input sizes, multiple times, and record the performance of each run. The code it tests, as listed in the script, can be found here.

The user should modify the values of these variables:

@RunsPerInputSize - the more runs at each input size, the more consistent the results

@InputSizeIncrement - the algorithm will start at this input size and also increment by it

@TotalNumberIncrements - the total number of different input sizes to test

For example, with @RunsPerInputSize = 2, @InputSizeIncrement = 50, and @TotalNumberIncrements = 3, the testing script will run the code to be tested with the following input sizes, in this order: 50, 100, 150, 50, 100, and 150.
