Just execute setup.sh as below:
$ ./setup.sh
It builds httpd for ab command that is used later and run bundle install, carton install, and gom install to install dependencies for each servers.
This repository includes several shadow server implementation written in the languages below:
You can run one of above as below:
$ bundle exec foreman start {perl,ruby,go}
It starts a shadow proxy server (port 8080) and nginx (port 8081 and 8082). If you dispatch a request to http://127.0.0.1:8080/, the request will be copied and dispatched to both of the ports on which nginx is listening.
I did benchmarking with the ab built from source instead of /usr/sbin/ab that was bundled with Mac OS X. For details, refer to the post below:
$ httpd-2.4.7/support/ab -n 1000 -c 100 http://127.0.0.1:8080/
