boomhammer is similar to wrk in that it is intended to be very simple. It does not perform as well as wrk, but improving performance is a goal: right now it's around 75% of what wrk does.

boomhammer -c <cpus> <url>

As of this writing, the URL must be an IP address.

boomhammer is extremely immature and is used to stress another product I'm working on. As time passes, more features will be added and performance will be improved.
