How to analyse thor output

I have been searching for a solution to do performance test on websockets. I found thor at github. I was able to setup a simple echo server in my localhost to test thor. I was managed to get it working. But I have no idea analyzing the thor output. Below is an example output I managed to generate using thor,

How can I analyse this result and set a benchmark for a Good server as well as low performing server? There isn't any documentation regarding the benchmarks in github. Can someone explain this in brief?
