Hi,
I am Avinash Mangipudi. I am learning JMeter at the moment. I am currently working for Larsen and Toubro Infotech at Bengaluru, India. There are a lot of load generation tools out there in the wild. Ability to generate as much load as needed and ability to modify the application to suit to your needs are 2 powerful concepts and JMeter provides both, for free.
Hats off to you JMeter.
