So have been out of touch lately but am getting back on track slowly.
Spent some time yesterday working on a benchmarking tool that generates graphs using Gnuplot. Thought it would be alot harder integrating it with ApacheBench but turns out I was able to get the vast majority of it done in about 4 hours. Hope to be pushing the tool up today and releasing the initial results on the blog (https://apichaining.blogspot.com/)
Promised some people of a push in the next week too so stay tuned and I'll try to get out some new code as well.
Current benchmarks on a run with 100 concurrency/5000 request bursts from a DEAD STOP (you will notice it hits approx 3000/rps in under 40secs):
