My exercise in learning go, this is a way to spin up hits against your webapp and see when it begins to smoke. up/down or +/- keys control the number of concurrent processes loading your url.

This uses the go wrapper around ncurses:goncurses. That can be a PITA to install on anything but the most recent ubuntu, apparently, so for obscure OS's like CentOS, Debian, or OS X see http://stackoverflow.com/questions/23975235/how-to-build-goncurses-on-os-x-centos-6/.
