“I deeply resent every second of my life I waste by thinking about load testing. All I ask is that our site be tested with a lot of traffic and without a bunch of BS for me to deal with. Thanks to LoadStorm, I need never again lose another moment to this insufferably tedious aspect of my job. I can feel the rage melting away.” - Shawn Miller, Web Developer, Woot.com
