Wordpress logged in user performance test with apache bench

wordpress-ab.sh

#!/bin/bash 

# For cygwin, APACHEBENCH could be /usr/sbin/ab2, else ab will suffice on linux/unix systems.
#
# This script is a fork of https://gist.github.com/electrawn/6815208
# 
# Fixed variable names
# Added concurrency and requests parameters
# Added curl and ab detection
