Getting Started WIth JMeter – YouTube

A very good introductory video from BlazeMeter, a performance & load testing cloud platform. I have been involved in some load testing for a multiple frond ends web application and I needed to use a free tool. Jmeter was recommended to me by a Java programmer I know at work and it turned out to be an excellent product.
