Detecting site performance anomalies using cURL

I recently participated in an IBM Webshpere Commerce Server deployment and was tasked with hunting down the source of some performance anomalies. cURL is a tool that has the ability to easily probe and collect detailed timing data using its many options. Below are the links I referenced to write my scripts that provided critical information and insight into the problem. I will add more detail here soon about what exact steps I used.
