figuring out ab testing

ab test script

#!/bin/bash
# This script will run a series of ab benchmarks and print them out to a files directory in a drupal site with the -w
# flag for easy web browser reading.
# Example usage:
# ./thisScript.sh -u 'ourpassword:todev' -d http://somedomain.com -o dir/towrite/to -f 'index/ something.php /content/node/xxxx'
