Hacxx Denial of Service was developed because the original tool "HTTP Query Tool" had a limitation. The limitation was that running in a continuous way will make the system slow down and the browser will hang up. This new version called "Hacxx Denial of Service" fixes the limitation of continuos queries and doesn't take a lot of system resources. In most computers it will run.
To take down a server the attacker should share this tool with his/her peers and all of them must run the program at the same time, generating lots of traffic to the site.
