I’ve been looking for something just like this. And thinking of writing my own just like you ;) I’m new to the whole web app area, coming from desktop: how would you best explain or pitch this to a newbie who understands the need but that’s about it?
Can it be used for once-off testing (per deployment we can handle n thousand connections / hour) or can it track performance and response speed so you can see how your servers are doing over time?
